Write 7 pages thesis on the topic isentropic expansion of ideal gas. By recording and using relevant pressure measurements with the help of suitable pressure gauges. The value of the specific heat capacity of air could be calculated. A relatively low percentage error in the readings and average value very close to the expected value (precision value) led to the conclusion that the experiment and the simulated adiabatic expansions were quite precise and reliable.

The specific heat (C) is critical because it determines how quickly a substance will heat up or cool down. It is a quantity of heat that is required to change the temperature of 1 kilogram of a substance by 1 degree Celsius. Specific heat capacity is a quantity central to the thermodynamic analysis of a substance.

In this experiment, the pressure was the best parameter to monitor and evaluate, and thus an equation relating the specific heat and the two pressure readings had to be derived. The derivation required the application of the first law of thermodynamics to the adiabatic expansion process and using the ideal gas law, making an assumption that the air behaves like an ideal gas.

In thermodynamics, an isentropic process is a process that takes place from initiation to completion without an increment or decrement in the entropy of the system. In other words, the entropy of the system remains constant. Entropy is a form of energy.

If a process is both reversible and adiabatic, then it is an isentropic process. An isentropic process is an idealization of an actual process and serves as a limiting case for an actual process. For an adiabatic process, there is no transfer of heat energy.

Before the experiment, the atmospheric pressure, P2 was measured using the barometer so as to determine the absolute pressures of the cylinder. In a similar way, the room temperature T1 was measured using the mercury in a glass thermometer.

The vessel was gradually pressurized to 5psig and the air supply turned off followed by the closing of the valve in order to isolate the compressed air inside the tank.&nbsp.

Create a 15 pages page paper that discusses ethical decsion making and the responsibilities and the conflicts of responsibilities of an administrator. “Decision making ethics is an area of ethics which pertains to making decisions” (Smith). Decision-making ethics are not limited to any specific area or industry, rather it is applicable to all fields of life including medical practices, teaching practices, schooling, and in solving workplace conflicts. Smith asserts, “Ethics are standards of conduct which can be applied to a wide range of situations, from medical practice to running a major company”. Making a decision is routine activity in the life of any person. A person takes many decisions in life regarding different matters and issues. An important thing in this regard is to analyze the positive and negative consequences of the decisions before their implementation because without proper analysis, a decision may not bring expected benefits to the people. Incorporation of ethics in the decisions is very important because it makes the decision justified and logical for every person. The practice of ethical decision-making not only makes people identify decisions with ethical impact but also makes them know how they can take an ethical and fair decision regarding any specific matter.

I need some assistance with these assignment. methods and research in science Thank you in advance for the help! Description mostly involves the collection of systematic observations, whereas prediction establishes relationships that exist amongst given variables, in other words, it can be said to be correlational research. Finally, explanation comprises the establishment of cause as well as affect relationships and is mostly done via experiments.

3. The main advantages of using the observational methods of data collection comprised of the fact that it is a prompt technique of collecting information since data obtained is usually readily available. Secondly, it is a cheap method in comparison with other forms of collecting data since it requires only observing and recording accordingly.

Thirdly, observation offers direct access to whatever social phenomenon is under consideration and thus does not rely on a third party to provide the required reports or information. Lastly, observation is able to assume different forms, from unstructured and informal approaches to tightly standardized, structured approaches, leading to yielding of related kinds of data, both quantitative and qualitative. Thus, observation can be readily applicable to a wide array of contexts (Frankfort-Nachmias & Nachmias, 2007).

4. Behavior is a term that is broad and basically is our way of communication. Human behavior can be categorized into 4 types which are. first is passive which is characterized by not requesting for what you want, bottling up anger within oneself, frequently saying sorry as well as saying yes when one wants to say no instead. Passivity usually does not have a place and time. The second type of behavior is aggressive and is mostly exhibited by shouting, intimidating, bullying, showing off as well as bossing around.

Aggressive behavior is all about dominance, control and this style of behavior stems out of one being afraid. The third type of behavior is assertive which basically is portrayed&nbsp.by individuals who are clear about what they want, are brave and honest with themselves as well as others.&nbsp.

Hi, I am looking for someone to write an article on sexeducation Paper must be at least 250 words. Please, no plagiarized work! REA 223 Jassim Al-Saiqal 28-2 Sex Education My presentation will be about sex education in schools, some of the problems society faces in regards to it, pros and cons, its effects on young students, and will take a comparative look at the way it is addressed in different cultures, as well as discuss some solutions. What is sex education? Sex education is a broad term used to describe education about human sexual anatomy, sexual reproduction, sexual intercourse, reproductive health, emotional relations, reproductive rights and responsibilities, abstinence, contraception and other aspects of human sexual behavior. The Problem Sex education is a major issue all over the world. The most widely debated point is whether to educate children about sex. Why do children need to know about sex? Should children learn about sex? At what age should they learn it? All of these questions are hotly debated. This topic has its pros and cons like any other topic, but which arguments are the most convincing? Let’s take a look at the way sex education is handled in two different cultures: American culture and Arab culture. Most people in the United States learn about sex in school, but in Arab culture they are more likely to learn from their parents. I think that makes a big difference. Where and how young people first learn about sex is very important. Bad sex education at an early age could lead to many problems. Fortunately, there is a solution. When introducing young people to a new idea, it’s important to be cautious and make sure they are ready. For example, you shouldn’t teach a five-year-old about the specifics of sex that he isn’t yet ready to understand any more than you would try to feed a baby solid foods before he is able to chew them. Kids should be guided into the topic at a pace that they can understand. It’s important to teach kids about sex carefully, in small steps. In the United States, six in ten teenage girls and more than five in ten teenage boys have had sexual intercourse before they turn eighteen. Of the approximately 750,000 teen pregnancies that occur each year, 82% are unintended. More than one quarter end in abortion. This is largely due to bad sex education in schools and lack of sex education in the home. However, between 1995 and 2002, the number of teens aged 15-17 who have had sexual intercourse declined by 10%. The rate of unintended pregnancies in women and girls aged 15-19 has declined steadily—from 117 pregnancies per 1,000 women in 1990 to 75 per 1,000 in 2002. This change can be attributed to a push to improve sex education and involve parents in their kids’ education about sex. We live in a culture that sends all kinds of messages about sexuality through the media. Kids can’t get through the day without seeing, hearing, or reading about sex on TV, in magazines, in music, and on the internet. It can be hard for children to understand what they are seeing, and there is plenty of opportunity for them to learn bad messages about sex. This is why sex education needs to begin in the home. Parents need to become proactive in teaching their kids about sex. It’s very important that parents make sure kids get the right messages about sex, and learn about their parents’ values. Schools alone can’t give kids perfect sex education. Study after study shows that kids who learn about sex from their parents first are much less likely to become sexually active at a young age, become pregnant as teens, and get an STD. It may be an uncomfortable topic for parents, but for the sake of their children, parents need to take responsibility for their children’s education about sex, before the media does it for them.
