Clausius-Clapeyron Equation Example Problem

Clausius Problem The Clausius-Clapeyron equation may be used to estimate vapor pressure as a function of temperature or to find the heat of the phase transition from the vapor pressures at two temperatures. The Clausius-Clapeyron equation is a related named for Rudolf Clausius and Benoit Emile Clapeyron. The equation describes the phase transition between two phases of matter that have the same composition. When graphed, the relationship between temperature and pressure of a liquid is a curve rather than a straight line. In the case of water, for example, vapor pressure increases much faster than temperature. The Clausius-Clapeyron equation gives the slope of the tangents to the curve. Clausius This example problem demonstrates how to use the Clausius-Clapeyron equation to predict the vapor pressure of a solution. Problem: The vapor pressure of 1-propanol is 10.0 torr at 14.7  °C. Calculate the vapor pressure at 52.8  °C.Given:Heat of vaporization of 1-propanol 47.2 kJ/mol Solution The Clausius-Clapeyron equation relates a solutions vapor pressures at different temperatures to the heat of vaporization. The Clausius-Clapeyron equation is expressed byln[PT1,vap/PT2,vap] (ΔHvap/R)[1/T2 - 1/T1]whereΔHvap is the enthalpy of vaporization of the solutionR is the ideal gas constant 0.008314 kJ/K ·molT1 and T2 are the absolute temperatures of the solution in KelvinPT1,vap and PT2,vap is the vapor pressure of the solution at temperature T1 and T2Step 1 - Convert  °C to KTK  °C 273.15T1 14.7  °C 273.15T1 287.85 KT2 52.8  °C 273.15T2 325.95 KStep 2 - Find PT2,vapln[10 torr/PT2,vap] (47.2 kJ/mol/0.008314 kJ/K ·mol)[1/325.95 K - 1/287.85 K]ln[10 torr/PT2,vap] 5677(-4.06 x 10-4)ln[10 torr/PT2,vap] -2.305take the antilog of both sides 10 torr/PT2,vap 0.997PT2,vap/10 torr 10.02PT2,vap 100.2 torr Answer: The vapor pressure of 1-propanol at 52.8  °C is 100.2 torr.

The Diversity of Over- and Under- Compounds

The Diversity of Over- and Under- Compounds The Diversity of Over- and Under- Compounds The Diversity of Over- and Under- Compounds By Mark Nichol Becoming familiar (or more familiar) with words beginning with over and under must include taking into account that these compounds can be both literal and figurative (or only figurative but rarely only literal) and can serve as various parts of speech. This post discusses some examples. Overboard has a literal meaning, referring to someone or something falling or being thrown from a ship or boat. (Board alludes to the wooden deck of a ship.) However, it also has the figurative sense of discarding an idea as if it were being thrown from a ship and of excessive enthusiasm; remarking that someone has gone overboard implies that the person is not on the firm footing of reality or sensibility. Similar, overthrow can be literal, as when describing an athlete throwing a ball too far, causing a teammate to be unable to catch it, as well as figurative, as with the sense of â€Å"defeat,† â€Å"depose,† or â€Å"upset.† Overhead originally meant, literally, what was above one’s head, but it also serves as a noun with several meanings: It can refer to a stroke that a player in a game of tennis or a similar sport makes over his or her head, to a ceiling in a marine vessel, or to basic business expenses that do not fall under the budget for a specific project. Overtime is the extra time after the regulated period of play in a competition (as to provide contestants with the opportunity to break a tie) or the standard workday or workweek (or, by extension, the pay for additional time spent working), but it can also refer, more casually, to when participants in a project work extra hours to complete it. Many words beginning with over-, such as overlook (which can mean both â€Å"provide a view from above† and â€Å"fail to see†) and overtake (â€Å"catch up to and pass†) are verbs, and some in which over is the second element of the compound are nouns transformed from verb phrases, including handover (â€Å"transfer†) â€Å"and takeover (â€Å"forced or otherwise hostile transfer of power†). Likewise, words beginning with under serve various grammatical functions. Underhand is an adjective referring to an action undertaken to avoid detection or to a motion made with the hand moving up from below the shoulder (and underhanded means â€Å"deceitful†), and as an adverb, it means â€Å"secretly† or â€Å"with an underhand motion.† Underline and underscore both denote a line inserted beneath one or more words to emphasize them but also serve as verbs with that literal meaning and with the figurative sense of emphasis. Understand is an outlier, in that it has only a figurative meaning; one does not use the word to refer to posing beneath something. (The Old English word for that action is undergestandan.) The sense is of standing close to or in the midst of something and thus being familiar with it, although under may stem not from the Old English preposition under but from the homonym related to the Latin word inter, meaning â€Å"between† (though the homonyms may be directly related). And though underworld once referred to Hades (as well as, occasionally, the earth, as being located beneath heaven), it came to refer to the lowest level in the social ladder and, by extension, the figurative collective of criminals, especially those in organized crime.

Talk about my Interest in Computer Science Personal Statement

Talk about my Interest in Computer Science - Personal Statement Example My objective is to become a member of the team who designs, valuable, useful and efficient software for the customers. The world of computers started fascinating me when I decided to work as a salesman in a computer store at Taiwan in the summer break of 2010.Apart from a reasonable salary, the store offered me a deep insight in the software programming that made up my mind of what I wanted to be in life. As I am a keen and an enthusiastic player of different computer games I was enthralled to see how the programming of different games was written. I began to develop a high understanding of software and hardware of a computer as my work involved assisting the experts with writing different software, repairing and assembling different models and versions of this remarkable technology. My working experience at this store made me reliable and consistent as I had to be very punctual with timings and has taught me to work as a team on a certain project. I believe I can utilize these skill s learned from my work experience in my education as well so as to make sure that I avail most of the opportunities available. This new curiosity of learning more never left me but in fact grew more intensely as time passed by. I came to learn and use a few software programs like Softimage|XSI ESP 3.0, Microsoft Visual Basic and Maya Personal Learning Edition. My aim is to see people enjoying the computer games and take pride knowing that I have contributed in creating the programming of the game. The knowledge I gained from working at that computer store allowed me to use my creativity to solve problems. My Taiwanese friends assisted me in whatever difficulty I faced regarding programming. My job turned out to be more like a training period to polish my skills and develop my interest in this vast field. My past educational background has nothing to do with computer science. My basic interest that brought me towards this profession was to see its widespread and practical use in the real world. Although I have a strong background in mathematics, my interest progressed in programming and computer because of my curiosity and passion to solve logical problems. Mathematics and computing has a strong connection as I came to realize that different concepts of mathematics such as vectors, logarithms and algebra are extensively used in computing. With the fine blend of computing and mathematics, I believe I can discover the unfamiliar for the betterment of the mankind. My sound foundation in math helped me to learn some computer languages such as VB and C++. Considering my interest in programming, one of my friend who is also a computer science programmer at UCI, helped me to learn how to write the APP program. APP is the software for Apple’s products like Ipad and Iphone. Apart from my educational background and experience I have gained through working I had always been an active student participating in the extra curricular activities. I am a good player of te nnis and have won many competitions in my school and club. I love to read and play video games on the computer as my favorite past time. Surfing on the internet to gain information and news about the recent hardware and software releases is my new hobby. I plan to have computing as my major in the university as my deep interest in the subject would guide me towards a bright

Home to Home - Essay Example The patient’s journey describes how a person experiences a disease from the initial realisation of the symptoms through the stages of presentation, diagnosis, treatment and adherence to the medication leading to cure, remission or death. Coronary heart disease results from the build-up in the arteries that blocks the blood flow and increases the risk for heart attack and stroke. Its main cause is the development of the heart complications that prevent it from receiving sufficient oxygen as well as nutrient rich blood. The most devastating symptom of the coronary heart disease is the development of abrupt cardiac arrest. Others include chest pain, short breath upon exertion, palpitations and dissiness. Some of the treatment measures administered to the patients suffering from coronary heart disease include aspirin, Beta-blockers and nitro-glycerine. Some of the preventive measures include adoption of a healthy lifestyle during childhood as well as reducing the risk factors. Cri tically analyse the sociological and psychological drivers that impact upon the patient’s journey through any health care setting. Sociological and psychological drivers share common interests in the management of the coronary heart disease. ... This procures the health care providers with an uphill task of undertaking primary research on these patients to ascertain these factors. One of the prominent factors affecting the psychological drive is the occurrence of stress (Ogden, 2009). High levels of stress delays the recovery rate of the patients suffering from the coronary heart disease. Patients under stress cannot strictly follow the treatment or the preventive guidelines. Patients suffering from coronary heart failure may also experience trans-generational and cumulative trauma. Most of them are normally resigned to the fact that they will acquire the disease genetically, making them ignore the keenness measures required for undertaking effective medication (Helman, 2007; Ayers, 2007). Most of the patients may also experience discrimination or racism that may lead to stigma. This slows down the recovery rates, with most of them succumbing to the ailments in severe cases. Sociological Drivers The prominent sociological fa ctor that negatively affects the patient’s journey for those suffering from coronary heart disease in a primary health care setting is the rise in the social media listening programmes (Gray, Degeling and Colebath, 2008; Barrett, Sellman and Thomas, 2005). The social media platform has provided patients with an electronic avenue for sharing the health information through utilisation of the speed of the Internet. Patients are able to become the members of the online family that connects them to the fellow patients and share information related to their conditions. The health care institutions can also tap on the information extracted from the online conversations to enhance

Evaluation of Mary Shelleys Frankenstein Essay -- Mary Shelley Franke

Evaluation of Mary Shelley's Frankenstein Form, Structure and Plot   Ã‚  Ã‚  Ã‚  Ã‚  Frankenstein, an epistolary novel by Mary Shelley, deals with epistemology, is divided into three volumes, each taking place at a distinct time. Volume I highlights the correspondence in letters between Robert Walton, an Arctic seafarer, and his sister, Margaret Saville. Walton's letters to Margaret basically explain his expedition at sea and introduce Victor Frankenstein, the protagonist of the novel. Volume II is essentially Frankenstein's narrative, told in his point of view, with much action, death, and many more characters. There are a few chapters within this volume in which the monster narrates his adventures while alone. Volume III displays Victor's death and the monsters portrayal as a desperate character. Robert Walton also writes one final letter to his sister, explaining the remainder of Victor's story. The story is written chronologically, but because Victor's narrative brings about a flashback, it seems as if Victor is found, then the story shifts ba ck in time to Victor?s youth and works its way back into present time. Volume I and Volume III are written in Walton?s perspective but Volume II is written mostly in Frankenstein's point of view. The work follows the patterns of an epistolary novel in that letters introduce the plot, the plot itself follows, and then letters to commence the plot end the story. The actual happenings of Frankenstein cover a two year period, but this does not include Victor?s narrative in Volume II. Characters   Ã‚  Ã‚  Ã‚  Ã‚  The characters that serve as narrators at some time during the story, Robert Walton Victor Frankenstein, and the daemon, may be considered believable. Walton describes his aspirations and limited findings, which lack room for inaccuracies. Frankenstein?s narrative, which seems somewhat farfetched at first with the introduction of the monster, proves itself as believable due to the raw emotions he expresses. The monster?s narrative is also believable because it just accounts for what he had done to fill time while alone in the woods.   Ã‚  Ã‚  Ã‚  Ã‚  Victor Frankenstein, one of the novel?s round characters, may be described as a creative, knowledgeable, and reserved man in his middle ages. The novel is unique in that Victor Frankenstein is both the protagonist and antagonist, consequentially creating a conflict of man versus himself. W... ...n my native   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  wood, nor known nor felt beyond the sensations of hunger, thirst, and   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  heat! Of what a strange nature is knowledge! (119).   Ã‚  Ã‚  Ã‚  Ã‚  The theme only heightens toward the end when Frankenstein sputters his dying words: ?Farewell, Walton! Seek happiness in tranquility and avoid ambition, even if it be the only apparently innocent one of distinguishing yourself in the science and discoveries. Yet why do I say this? I have myself been blasted in these hopes, yet another may succeed.? (215). It is only appropriate that his dying words confront the main them of the story. In essence, Frankenstein is confirming that knowledge is, in fact, dangerous, but even more dangerous is not pursuing knowledge for if one were to succeed, he would open that field up to all of mankind. Significance of Title There seems to be no true significance of the title Frankenstein. It seems merely to be named after the story?s main character, protagonist, antagonist, and, of course, its roundest character. Works Cited: Shelley, Mary Wollstonecraft. Frankenstein; or, The Modern Prometheus. Ed. D.L. Macdonald and Kathleen Scherf. Peterborough: Broadview Press, 1994.

Ethics, What Is Ethics Essay

What Is Ethics? Ethics is the part of philosophy that deals with good and evil. Ethics tries to answer questions like: †¢What actions are good? What actions are evil? †¢How can we tell the difference? †¢Are good and evil the same for everyone? †¢How should we make hard decisions that might help or hurt other people? The Four main studies of ethics are; †¢Meta-ethics, about the theoretical meaning of moral propositions and ethical opinions; †¢Normative ethics, an abstract set of principles to distinguish right from wrong †¢Applied ethics, about how moral outcomes can be achieved in specific situations; †¢Descriptive ethics is the study of people’s beliefs about morality, what ethical beliefs people have; Ethics seeks to resolve questions dealing with human morality. Meta-ethics is a field within philosophy that seeks to understand the nature of normative ethics. The focus of meta-ethics is on how we understand, know about, and what we mean when we talk about what is right and what is wrong. It’s the mean of ethical opinions, but the opinions have to be justified. Normative ethics is the study of ethical action. It is the branch of philosophical ethics that investigates the set of questions that arise when considering how one ought to act, morally speaking. There are two types of normative ethics; Relativist and absolutist. Relativist ethics have flexible rules surrounding ethics so to get the best possible outcome for everyone where as with absolutist views, the rules are non negotiable, you must follow them no matter what the outcome. Applied ethics attempts to apply ethical theory to real-life situations. Applied ethics is used by individuals facing difficult decisions. The sort of questions addressed by applied ethics include: â€Å"Is getting an abortion immoral?† â€Å"Is euthanasia immoral?† â€Å"Is affirmative action right or wrong?† â€Å"What are human rights, and how do we determine them?† â€Å"Do animals have rights as well?† and â€Å"Do individuals have the right of self determination?† It is the study of human morals, and issues of moral concerns. Applied ethics are open to debate. Descriptive ethics are the ethical beliefs people actually have. Its examination of ethics doesn’t start with a preconceived theory, but it investigates observations of actual choices made by people in practice. Some philosophers rely on descriptive ethics and choices made and unchallenged by a society or culture to derive categories, which typically vary by context. This can lead to situational ethics and situated ethics. Utilitarianism; is an ethical theory that argues the proper course of action is one that maximizes overall â€Å"happiness†. Jeremy Bentham and John Stuart Mill are influential supporters of this. Bentham says ‘it is the greatest happiness of the greatest number that is the measure of right and wrong’. This form of utilitarianism holds that what matters is the total happiness; the happiness of everyone and not the happiness of any particular person. John Stuart Mill, in his exposition of hedonistic utilitarianism, proposed a hierarchy of pleasures, meaning that the pursuit of certain kinds of pleasure is more highly valued than the pursuit of other pleasures. Deontology; deontological ethics or deontology (from Greek â€Å"duty†) is an approach to ethics that determines goodness or rightness from examining acts, or the rules and duties that the person doing the act tried to fulfil. In deontology, an act may be considered right even if the act produces a bad consequence if it follows the rule that â€Å"one should do unto others as they would have done unto them†, and even if the person who does the act lacks virtue and had a bad intention in doing the act. According to deontology, we have a duty to act in a way that does those things that are inherently good as acts, or follow an obligatory rule (as in rule utilitarianism). For deontologists, the ends or consequences of our actions are not important in and of themselves, and our intentions are not important in and of themselves.
