Define the following in your own words: 1. Adhesion 2. Triple Point 3. Cohesion 4. Critical Point 5. Sublimation 6. Allotrope (and give an example) 7. Lattice Energy 8. Surface Tension 9. Polarizability 10. Normal Boiling Point
Study how to use the Clausius-Clapeyron equation in EXAMPLE 12-5 on page 516 in the Petrucci Textbook. Then solve these problems:

1. A handbook lists the normal boiling point of isooctane as 99.2°C and it’s enthalpy of vaporization as 35.76 kJ/mol. Calculate the vapor pressure in atm of isooctane at standard temperature.
….. you should get an answer of 0.0565 atm. Work it out so you know how!

2. Cyclohexanol has a vapor pressure of 10.0mmHg at 56°C and 100.0mmHg at 103.7°C.
Calculate it’s enthalpy of vaporization, ΔHvap.
….. you should get an answer of 49.7 kJ/mol. Practice until you get it!

3. The normal boiling point of acetone is 56.2°C and its enthalpy of vaporization is 25.5 kJ/mol.
At what temperature does acetone have a vapor pressure of 375mmHg?
….you should get an answer of 33°C. Keep trying until you do!

Data Table for Hydrazine, N2H4

4. Use the data from the table above to determine how much heat is required to convert 25.00ml of liquid hydrazine at 25.0°C to hydrazine vapor at its normal boiling point.
Hints:
1. Use hydrazine’s density and molar mass to determine the amount of moles to be vaporized with the given volume. Use a periodic table to get any information you need. 2. Use the Clausius-Clapeyron equation to solve for hydrazine’s ΔHvap. 3. QVap = (moles)(ΔHvap) Q = heat, so QVap is “heat required to vaporize” 4. QHeating = (moles)(heat capacity)(ΔT) ΔT= change in temperature
QHeating= The heat needed to go from 25.0°C to the boiling point. 5. The heat(Q) required to convert 25.00ml of liquid hydrazine at 25.0°C to hydrazine…...

...staff that they acknowledge everyone they encounter.”(Planetree, 2012) I decided to focus on providing abundant information for one aspect of our project. Radiology departments are infamous for long wait times, and there were only dated magazines to choose from in our old waiting area. In an article about the opening of the Jay Moynihan Center for Gastrointestinal health in Upper Manhattan, The New York Times reports “A hospital’s own studies had shown that inferior waiting rooms topped the list of patients’ complaints about their care. Waiting should be more active.” (Karush Rogers, 2005) I discovered through conversations with the VA Medical Media Department that the team could order informative brochures describing radiologic procedures in lay terms. We could order as many brochures as we wanted to educate the patients at no cost to the department. These brochures are now handed to the patients when they check in for a procedure. For example, if you were going to radiology and you had a carotid ultrasound scheduled, upon check in you are given a brochure describing the carotid ultrasound. All of the procedures that are done at the VA Radiology have a matching brochure and they are all available for perusal in a rack in the waiting room. Many patients that come to radiology have little understanding of the procedures they are undergoing, and these brochures build a foundation for education...

...Informative Speech Introduction 1. In the contemporary world, underage drinking has become a global phenomenon especially in the developed countries such as in the US. As a result, the Oklahoma State has taken various measures to curb the vice. This is the reason behind the enactment of the Underage drinking laws-Social Host Law. The law was enacted in order to; a) Minimize the circumstances that lead to death of a minor or suffering physical injuries b) To enhance concentration at school especially for the minors c) To make societies responsible for their young people and develop virtues that would lead to productive work in future d) Promote healthy social life Body (Translation: I will begin by outlining the aspect of underage drinking, Oklahoma’s Social Host law and specifically where Cody’s law emanated from) 1. Consumption of alcohol by the young people in the US is prohibited especially for people who are below 21 years. However, despite the minimum age that is set for people who buy alcohol being 21 years in all the states, the legal requirements varies significantly. For instance: a) Wagenaar and Melvin argue that some states have exceptions whereby they allow some individuals who are below 21 years to consume alcohol (37). This indicates that the laws are not uniformly implemented across the states. b) In Ohio State, the social host law has not been limited to the drinking parties by the underage. Therefore any action that is undertaken by an underage......

...COMM 10- Elements of Public Speaking Master Make-up Artistry (Informative Speech) Specific Purpose Statement: To inform my audience about the three major types of make-up needed to be a master make-up artist. Central Idea: High Fashion, Character and Prosthetic/Special effects make-up are all skills required in order to be considered a master make-up artist in the industry. Introduction When I was about 3 or 4, I remember watching my mom put on her make up and being completely fascinated by it. Well being the curious little kid that I was, I decided to be exactly like mommy and do what she did. Bad idea! I ended up in the emergency room because I had super glued by eyelashes together. Needless to say, my first experience with “make-up” was not what I’d call great. Since then though, I have grown to love make-up and so I started to wonder what makes someone a master of makeup. Body I. High fashion make-up is the foundation or rather the basics of all three make-up types. A. It’s used to identify a person’s skin type, bone structure, eyebrow and face shape. 1. Identifying all these factors into helping determine what products to use on an individual. B. Its application is solely for beauty purposes. 1. You mostly see this kind of make-up done in editorial spreads in magazines, on television, in films or on the runway. II. Character make-up is to help define and develop the characteristics needed for a certain role. A. This process helps......

Persuasive and Informative Speech

...kinds of speech. There are three major classifications of speeches i.e informative, persuasive and commemorative. However this assignment is going to focus on two kinds of speeches, i.e. the informative speech and persuasive speech particularly on the differences. In order to fully understand the differences between the two I will explain briefly what each of them mean. According to ask.com, An Informative speech is one that is written to present fascinating and useful information to increase the knowledge of your audience. A good informative speech features a topic that should be fun and interesting, and one that makes it easier to capture the audience's attention. Persuasive speech comes from the word persuade or persuasion which implies an argument or other statement intended to influence one's opinions or beliefs. There are quite a number of differences between the two kinds of speech. One of the major differences can be highlighted from the purpose, fully understanding the information or purpose of the speech will help signify the difference because depending on the purpose different rhetoric speeches will be used. E.g. In an informative speech there is more evidence and less Pathos. Speaking in order to inform As the name suggests informative speeches have the main purpose of informing, however how this information is given determines if it is clearly an informational speech or not. The goal of informative speech is to communicate ideas in a way that your audience......

...COMM 100-06 Informative Speech Outline Title: MEDIA AND YOU Speaker: Specific Purpose: At the end of my speech, the audience will be able to take steps to ensure they and their loved ones are using social networking sites to their full advantage. Central Idea: Time is money and a huge aspect in our lives which we cannot rewind so we must use it wisely and efficiently especially in regards to the time spent on social networking sites to have a positive impact on our lives. Introduction: According to the Nielsen Company survey back in August 2009 social networking and blogging sites accounted for 17% (about one in every six minutes) of all time spent on the internet. That statistic is three years old, as of today that percentage has increased rapidly due to the almost one billion members on Facebook alone, while Twitter is growing at an increasing rate. In the wise words of the great Jim Morrison “Whoever controls the media, controls the mind,” are extremely valid because everything we talk about in our daily lives has been influenced by another person whether it be reading a newspaper, listening to the radio, or watching television. In the ensuing few minutes I will be discussing the positives, and negatives of social networking while also how we can incorporate the benefits into our lives to make social networking a huge advantage in our lives. Body: I. Disadvantages of Social Networking A. Privacy Issues 1) Stalkers and complete strangers can view......

...Ma. Sarah Katrina F. Santos June 16, 2014 11229888 SPEECOM - C32 Informative Speech How many of you thinks that having more customers is better than having fewer customers for a business? Can I see a show of hands? Alright. I presume that for those who said yes, which is the majority, raised their hand for the same reason. More customers mean more people buying and more people buying mean more profits for the company, isn’t it? Sounds sensible but I hate to break it to you but those of you who said yes are wrong. Today I will transform that thinking to exactly the opposite. I will introduce based on a new study the idea of ‘less is more’. Focusing on a smaller number of customers could help a company speed up growth, increase profit and improve long-term health. I am going to talk about how top companies gain customers, how they keep them and how these customers help them in expanding their business. They don’t need a lot of customers, just the right ones to keep them on top. First point is, fewer customers can speed up the company’s growth. Would you believe that some companies actually go out of business because of too many customers? Yes, that is true. The problem with these companies is they get very overwhelmed with the influx of customers that they forget to establish a connection with their customers. According to Forbes, this is one of the top 5 reasons why 8 out of 10 businesses fail - because they are not really in touch with their......

Start noticing how your tone of voice affects how others respond to you and try using tone of voice to emphasize ideas that you want to communicate. Use Good Eye Contact- When people fail to look others in the eye, it can seem as if they are evading or trying to hide something.
