The heat energy produced by propanol Essay Example

The heat energy produced by propanol Paper The energy released by a fuel depends on two things. Firstly the number of bonds to be broken and made and secondly the type of bonds involved. Therefore from the preliminary work I can see that propanol has similar type bonds to ethanol, but it has more of them. This means that proponal will use more energy to break the bonds and; therefore more energy will be released to make more new bonds. Also, the greater the surface area and the greater the force of attraction between the molecules, will make it harder to vaporise. Therefore more energy will be released. Fair Test I would like to gain the most reliable results possible using the equipment and conditions provided; therefore I will have to consider certain factors, which if I do not control, may enforce my results to become less reliable. I will, * Keep a constant water temperature at the beginning. * Keep the distance of the copper can away from the flame at 5cm. * Have a constant water mass. * Keep the temperature from which the experiment is terminated fairly constant. * Stir the water with the thermometer before each temperature reading, which will distribute the heat evenly. Results Fuel Mass of Fuel Used Average Ethanol Analysis I will use the averages for ethanol and propanol to work out the total energy transfer and then I will use this to find the mass of fuel burnt per mole. The workings below show what I found out and what this suggests. Ethanol Q = M x C x t The letter Q is the energy in joules and what I want to find out, M is the volume of water in the copper can, C is the specific heat capacity of water and At is the rise in temperature during the experiment. All of these were kept the same throughout the experiment; therefore, M = 100cm3 C = 4. 2 t = 200C This gives the equation,Heat produced.

In order to work out the number of moles in 8400KJ I will use the equation, Number of Moles = mass/Relative Molar Mass If I put these numbers into the equation to give, Moles of ethanol burnt = 1. 4g/46 = 0. 03 moles. I will then use this to calculate the energy in one mole, 8400/0. 03 = 280000J = -280KJ Propanol I will use the same equation using the same numbers as before as they were kept the same in this experiment as well. This should give,Heat ProducedThe mass of propanol burnt is 1g and the relative molecular mass of propanol is 60, which I again worked out beforehand in my plan. I will use the equation, Number of Moles = mass/Relative Molar Mass I will put the numbers in the equation appropriately to give, Moles of propanol burnt The above figure can be used to work out the energy in one mole0KJ I did not use 0. 4 for the propanol average, because it does not follow the general trend; therefore it is anomalous. If I had included this result it may have affected my results slightly. The results that I obtained clearly show that the propanol did have the greatest energy loss; therefore my prediction was correct and theoretically my preliminary work was very successful in helping me gain the correct prediction. This is shown whereby for ethanol the energy give out per mole is -280KJ, whereas propanol gives out a slightly bigger -420KJ. From this experiment I have learnt that if there are too many carbon atoms present in a fuel then the energy given out as heat through combustion is increased, whereas if there are too few carbon atoms then the energy given out as heat from combustion decreases. If I compare my results with my preliminary work there is an immense difference in figures, whereby for ethanol the energy produced from one mole using the scientific figures is -1031KJ, whereas my results show that there is -420KJ of energy released. Also the scientific results for propanol are -2076, whereas my results show that for proponal -420KJ of energy was released. This significant difference was probably due to the extreme mass of heat loss during the experiment from the copper can, the spirit burner and the water; therefore less heat was transferred to energy. Also average bond energies shown in the data book were taken at 250C, whereas I took my results at a temperature of 200C, which means that a higher temperature the molecules would have had more energy as the bigger the temperature the faster the reaction; therefore more energy would have been transferred as heat after the breaking and making of the bonds. Evaluation I think that my experiment was fairly successful considering the limited equipment and conditions, as I managed to gain a set of fairly reliable results in order to draw a firm conclusion. There was only one anomalous result, which happened when testing the propanol whereby there was a result of 0. 4; therefore I did not include this in my average taking. This could have occurred for a number of reasons these are, The amount of water put into the can may not have been measured completely accurately because of the way the level of the water is seen in the measuring cylinder.   There may have not been a totally consistent height above the spirit burner. The spirit burner was not covered up during experiment; therefore the fuel could have evaporated. The length of the wick varied.   Heat could have escaped out of the sides of the spirit burner during combustion.   The copper can meant that it absorbed and transferred heat well but it lost heat to the air as well. These reasons could have had an slight effect on my results overall, whereby it will have made my results lower than the theretical results, as shown in my analysis. If I were to do this experiment again I would, Weigh the water in the copper can using burette instead of a measuring cylinder. Measure the distance between the can and the sprit burner between each fuel burnt.   Cut the wick to the same length after each fuel is burnt.   Insulate the copper can at the sides. User a Bomb Calorimeter so that draughts can be prevented and so that there is restrictions to the heat lost. The diagram below shows what the bond calorimeter would look like and how it would be set up. I think that despite the problems that occurred I still managed to gain a fairly reliable set of results in order to imply whether the energy loss for ethanol or propanol was bigger. If I were to experiment further I could experiment with a much wider range of fuels to see whether their energy loss is bigger then propanol. Also I could investigate other factors that affect the energy loss from combustion, such as, the length of the wick, the heat source and the heat capacity. In doing this I can broaden my understanding in this section of chemistry.

Free Essays on A Brief History on Comics

Comics: In the Beginning The modern comic, as we know it, began in Joseph Pulitzer's New York World on February 17,1895. The comic, drawn by Richard F. Outcault, was based on the life of Mickey Dugan, an Irish immigrant child in the city. Although the strip had no name, people have dubbed it the "Yellow Kid" because the nightshirt worn by Mickey Dugan was the projection for an experiment in yellow ink by the newspaper. Eventually the comic came to be known as "Hogan's Alley." Soon comics were recognized for the selling potential and were published in newspapers all over the world. After the success of the World, a competitor, William Randolph Herst of the New York Journal, hired Outcault to draw Hogan's Alley for Hearst's Journal. The World continued publication of the strip using a new artist, and both papers were featuring the "Yellow kid." This led to people referring to the two papers as the yellow papers. And as the battle between the press lords became more intense, peop! le began calling it yellow journalism which now has come to mean overly sensational journalism. Although Outcault won the battle over the rights of "Yellow kid," the mass marketing began. The cartoon was everywhere. Products were being produced, even cigars, bearing the "yellow kid." Soon the comic revolution began, and strips were published all over. Of these comics, "Katzenjammer Kids" drawn by Rudolph Dirks in 1897, was one of the most popular and first to regularly use voice balloons for dialogue. Outcault also continued drawing, and began a strip called "Buster Brown" which was to be a tie between the comic strip and the comic book. The mass marketing continued, and "Buster Brown" had his own line of shoes (McHam). Until 1907, comic strips ran only on Sundays. In 1907, the first daily strip appeared.

Chemistry Review of pOH Calculations

Chemistry Review of pOH Calculations Sometimes you are asked to calculate pOH rather than pH. Heres a review of the pOH definition and an example calculation. Acids, Bases, pH and pOH There are several ways to define acids and bases, but pH and pOH refer to hydrogen ion concentration and hydroxide ion concentration, respectively. The p in pH and pOH stands for negative logarithm of and is used to make it easier to work with extremely large or small values.  pH and pOH are only meaningful when applied to aqueous (water-based) solutions. When water dissociates it yields a hydrogen ion and a hydroxide. H2O ⇆ H OH- When calculating pOH, remember that [] refers to molarity, M.

Now press log. Remember your answer is the negative value (-) of this number.pOH - (-4.37)pOH 4.37 Understand Why pH + pOH = 14 Water, whether its on its own or part of an aqueous solution, undergoes self-ionization which can be represented by the equation: 2 H2O ⇆ H3O OH- Equilibrium forms between the unionized water and the hydronium (H3O) and hydroxide (OH-) ions. The expression for the equilibrium constant Kw is: Kw [H3O][OH-] Strictly speaking, this relationship is only valid for aqueous solutions at 25 °C because that is when the value of Kw is 1 x 10-14. If you take the log of both side of the equation: log  (1 x 10-14)  Ã‚  log  [H3O]  Ã‚  log  [OH-] (Remember, when numbers are multiplied, their logs are added.) log  (1 x 10-14)  Ã‚  -  14-  14  Ã‚  log[H3O]  Ã‚  log  [OH-] Multiplying both sides of the equation by -1: 14  Ã‚  -  log  [H3O]  -  log  [OH-] pH is defined as  -  log  [H3O] and pOH is defined as -log  [OH-], so the relation becomes: 14 pH - (-pOH)14 pH pOH

Design pattern Assignment Example | Topics and Well Written Essays - 1500 words

Design pattern - Assignment Example These receiver commands are string in nature. In this algorithm, all the commands that will be visible to the user are subclasses to the moveable command abstract class. The three objects which are moveable which include the rook, bishop and the knight are able to be moved to and from the different positions on the board. The codes for each segment of the class are given in the chart above. This design pattern models a one to many dependency between the objects in the algorithm. This design pattern is creational in nature and connects the state of an observed object the subject with many observing objects and the observers. The square view model is related to the composite class in the algorithm which in turn is related to the color background and the square state of game. The square view model object is able to position the board which is ten passed to the composite class which sets the required state of the square. The color background class sets the background color of the object and finally the square state model of the class is changed as set by the user. The main use for this approach in programming is to ensure that we maintain consistency across the states that appear to be redundant in the code and also optimize the changes so that the consistency necessary is maintained. In this approach to in pattern design, the consistency is maintained using three main var iants: The square view model object acts as the publishing notification which then subscribes to both the color background and the composite objects which then push the notification to the subscribing notification for updating. If we take into consideration a user interface toolkit that is capable of supporting multiple number of applications and controls, the game view object sets up a game on the user interface which then clears the board to create a new game. The new game has two main components sub objects which include the controllers for the object and the

The Role of the Leader in Evaluating Data to Improve Quality and Assignment

The Role of the Leader in Evaluating Data to Improve Quality and Safety Paper - Assignment Example Despite the increased attention within the healthcare industry to facilitate reimbursement to the best available intentions for managing patient falls, the rates continue to escalate, which puts the patients and their caregivers at risk. The facts as depicted in the core of this study indicate the alarming rates, which falls and other critical developments in the care facilities continue to influence the role of the nursing leaders. The facts as presented remain undeniably high compared to the rates of the manageable cases within this case as the report indicates. The telemetry unit in this case is observing an increasing rate of falls of patients. For instance, compared to the average age, which is at 72.4 years, this rate of falls is quite difficult to note the cause. Secondly, the majority of the cases of the patient falls as depicted in the case apply to the patients with diuretics. The patients depict aspects of confusion and disorientation, constituting 12% of the patients with such secondary diagnostics. This establishment is vital to the establishment of workable plan. Additionally, it is also observable that most of the cases of the patient falls occur during the early morning hours. The patient reports indicate that a significant majority of the patients experiencing falls occurs from 3:00 AM to 11:00 AM. Moreover, it is also notable that the minimum number of patient falls occurs in the afternoon hours. These observations indicate the need to evaluate the causative factors contributing to this trend in within the unit. From observing the developments in the fall rates, it is also notable that the average falls is on the rise for each of the days within the hours described. The nurses that recall the incidents when the patient fell indicate that the patient fall rates increase with increase in age. This observation means that the plan to address the cases of patient falls need to consider the vulnerability and co-morbidities

Patriotic reverence for the history Essay Example for Free

Patriotic reverence for the history Essay Patriotic reverence for the history of a nation often does more to impede than toencourage progress History always brings with itself lots of experience. People always learn from their past. Butis relying on the history nation the right path to progress? Does our past always teach us theright lessons? What we do today will be past someday. Does that mean we will always end updoing right if we follow our history. The answer is no. Showing high patriotic reverencecannot always be the right path for a nation’s progress. Relying on history for our current needs would be nothing more than intuition. The situationwe have at our hands can be very different from that experienced in the past. The demandthen becomes to handle it with new ways and techniques. For example maintaining peace inthe world today is the most important factor for any country’s progress. If we look at history,nations earlier had a tendency to acquire and conquer as much as they can. The Germans inthe World War II killed millions of people in their neighboring countries in thirst of more andmore power. The world has witnessed many wars that have hampered progress. Thus theneed of the hour for all nations is to sit down and talk. Nations now need to have a friendlyattitude towards each other for maintaining progress. Nations have signed peace treaties,which includes the nuclear proliferation treaties. The nations have now started thinking of progress on a global prospective. The economic progress of a nation particularly developing countries has also been verydifferent from the past. The trends and graphs are very different from that in the past. Thecorporate world has been developing and expanding exponentially. The economic market isnow governed by new rules with no excerpts from the past. So, the demand of the hour cannot be met by completely relying on the past. But just learningfrom our experiences. If we refer to our past, we need to draw proper analogies between thetwo time variant situations. But this can be a very difficult task as the scenario and theessence of things for todays world are completely different.

My Philosophy of Teaching Essay -- Graduate College Admissions Essays

My Philosophy of Teaching    As an undergraduate, I was a teaching assistant for several psychology courses, including introductory psychology, behavioral statistics and research methods. My first teaching experience was as a Teaching Assistant for statistics; I now believe that this is where my individual teaching philosophy began taking shape.    As a teaching assistant for behavioral statistics, I was exposed to the student's outlook on the material, in which a lack of enthusiasm for statistics was undoubtedly portrayed. The message was clear: seemingly uninteresting and inapplicable material equals uninterested students. The students that I assisted did not believe that this material would clearly impact their lives; they did not see a meaning or purpose in comprehending or learning the material aside from dutifully collecting a grade at the end of the semester.    Even as an undergraduate student, I was saddened by the lack of enthusiasm by other students for learning a topic that I felt could benefit everyone. Since that time, I have slowly develop...

Business Unit 3 Constraints of Marketing

Constraints of marketing Legal aspects There are four legal aspects that can limit and constrain your marketing, these are the sales of goods act 1979, and this law means that all products must be ‘as described’ of ‘a reasonable quality’ and be suitable for everyday purpose and also any specific purpose agreed. E. g. a waterproof coat must be waterproof. Another legal aspect is the trade descriptions act this means that a product cannot be sold by misleading the buyer, in the way the product was made, what it is made of or where and when it was made.E. g. You cannot say something is handmade if it is not, and a hair dryer made for drying hair, must actually dry hair. The consumer credit act 2002 protects consumer’s rights when they buy goods on credit. Traders who offer credit must have an OFT (Office of Fair Trading) licence, this deals with the method of calculating APR (Annual Percentage Rate) the form and content of the agreement, and lenders guid elines. When lending money, businesses much have interest rates clearly stated and cannot change them after you have signed up.The Data Protection Act means that any information stored by marketers must only be used for the purpose stated when collected, it must be accurate and up to date, not kept longer than the period of time stated, and obtained fairly and lawfully. It must be kept up to date as if someone passes away you should not call asking for them. Also your information is protected from unauthorised use, and cannot be passed on to other companies without your permission. The information stored is available for your inspection and correction upon your request.Voluntary codes A voluntary constraint is when a company voluntary says they will never do something or they will always do something. This could include signing a code of practice stating certain behaviours ethically, even though it cannot be legally enforced. The ASA (Advertising Standards Authority) overlook advert isements in the UK and have been controlling non-broadcast ads for nearly 50 years. They say adverts must be decent, legal, honest, and truthful. The ads online are also subject to these rules.Most companies sign up to the ASA and then on follow their rules, if the rules are broken they are not breaking the law but the ASA will publicise this and show everyone what has happened and what they have done. 2397 ads were changed or withdrawn in 2009 by the ASA. E. g. The advert, for the Ford Ka's ‘Evil twin' featured a pigeon-bashing four wheeler that brought the wrath of animal rights activists across the country, meaning the advert never even made it to air in the UK. Pressure groups and consumerismPressure groups are groups of people who share the same interests in a business or product; these groups can persuade or force businesses to make changes to their products or services. E. g. cancer research focus on the particular smoking issue and attempt to reduce smoking. And Friend s of the Earth are a multiple cause group who seek to influence the decisions made concerning the environment. Greenpeace seek to promote environmental issues to its members and supporters. Marketing must include promotion to get people intrested. Consumerism is ‘a social movement seeking to augment the rights of buyers in relation to sellers’

How Religion Affects Society Essay

More generally, social scientists are discovering the continuing power of religion to protect the family from the forces that would tear it down. 13 Professor Bergin’s summary was echoed two years later by nationally syndicated columnist William Raspberry: â€Å"Almost every commentator on the current scene bemoans the increase of violence, lowered ethical standards and loss of civility that mark American society. Is the decline of religious influence part of what is happening to us? Is it not Just possible that anti-religious bias masquerading as religious neutrality is costing more than we have been willing to acknowledge? † 14 Other reviewsl 5 also list the positive effects of religious belief and practice in reducing uch problems as suicide, substance abuse, divorce, and marital dissatisfaction. Such evidence indicates clearly that religious practice contributes significantly to the quality of American life. Given this evidence, Congress should: Begin a new national debate to help renew the role of religion in American life; Ask the General Accounting Office (GAO) to review the evidence on the beneficial effects of religious practice in the relevant social science literature and report its findings to a national commission formed to promote the consideration of religious Fund federal experiments with school choice that ractice among U. S. citizens; include religiously affiliated schools; Pass a sense-of-the-congress resolution that data on religious practice are useful for policymakers and researchers as part of the public policy debate; and Mandate a census question on religious practice. It religious practice in America. The President should: Appoint Judges who are more sensitive to the role of religion in public life, with the Senate ensuring that such is the case by ascertaining the stand of Judges on matters of religion and its relationship to the Constitution; Direct the Bureau of he Census to record levels of religious practice in the census for the year 2000 (time is running out for preparation of the census questionnaire); and Issue a directive to all federal agencies making clear that cooperation between government entities and the social, medical, and educational services of faith-based organizations does not violate separation of church and state. The U. S. Supreme Court should: Review the decisions in which it has changed the laws of the land by changing commonly held beliefs regarding the Constitution and religion and send to Congress hose that should have been the object of legislative action rather than Judicial reinterpretation. America’s religious leaders should: Be much more assertive in emphasizing the contribution of religion to the health of the nation and in resisting efforts to minimize religion in public discourse; Make clear to their congregations that they are contributing not only to their own welfare, but also to the well-being of the nation by their regular attendance at religious worship; Take special care of the religious formation of children, especially during the transition period from childhood to adolescence, when they are ost likely to lose their religious faith; Recognize that the church in the inner city, especially the black church, has a vital role to play in helping its people escape from the degrading culture of inner-city poverty;

Reality Shows

Reality Shows Reality shows, why do we like them so much? I started thinking about this question, and then I though about how many I actually had watched. Reality shows has become a big trend in our society today. People can become famous for almost anything, and a lot of people seem to think that being in a reality show is the biggest thing that can happen in life.I think all of us have though about being famous at some point in our life. How nice it would feel to be that athlete, singer or actor that everyone knows. Maybe you always dreamed about becoming a model, a writer or why not just get married to a rich famous man or woman. I don't see this as something wrong, I think that everyone, at some point, wishes for that feeling of being someone important and well known. An easy way of having 15 minutes of fame today is to be in a reality show.English: This is a production sound mixer Lance Lu...Today you can probably turn on the TV at any time of day and be able to see a reality show. The marke t has exploded, and they are almost taking over TV.We might think that reality television are a new phenomenon, but the truth is that the first reality show debuted in 1973, and it was called An American Family. On Thursday, January 11, 1973, the first broadcast of An American Family changed television history forever. The Loud family were from Santa Barbara, California and consisted of Mother Pat, Father Bill, and their five children Lance, Kevin, Grant, Delilah and Michele.It was a fascinating documentary series. The members of the Loud family opened up their home and lives for seven months to producer Craig Gilbert, who shot 300 hours of footage. Only 12 hours...
