Below are two links for the videos on Heat and Temperature.  You may look at them now or later or during our next online session.  I will not be giving the data of the experiment. You, the student, need to watch the video to get the data while watching the video and record in your data sheet. Rest of the parts, calculation, plotting graph etc should be as usual. You can actually “do” the lab now or anytime before our  online class.  Just watch the two videos and “take” the data.

Read the case “Am I Really a Leader?” and put yourself into the situation being presented.  Answer the questions completely by using your educated observations, supported by the text book and two or more sources.  The Case write-up is to be 2-3 pages, double-spaced with indented paragraphs, 12-point font and proper APA format.  Include a title page, cite your sources and provide a List of References.  Complete  the “Authentic Leadership Self-Assessment Questionnaire” and write a 1-page reflection about the scores you received on the instrument.

While the previous discussion asked you to consider the impact of the first part of the 20th Century upon our lives, I firmly believe that nothing has done more to shape the America we live in than the Cold War. The profound impact on our government, foreign policy, society, and culture are still being felt today. For this discussion, I would like you to answer the following three questions:

1) What were the greatest “costs” (negative consequences) of the Cold War for the United States of America?

2) What were the greatest “benefits” (positive outcomes) of the Cold War for the United States of America?

3) In your opinion, based upon your previous answers, was the Cold War ultimately a positive or negative experience for the U.S.?

Please make your responses at least one substantial paragraph long each and include specific historical details, processes, and/or people to support your arguments.

Please use these property tables attached in the additional materials section to answer these two questions:

1) An inventor proposes this method for cooling down water in an insulated bottle: fit a piston tightly against the water surface, and then pull the piston so that some of the water vaporizes and absorbs heat from the rest, which is still liquid. Calculate the work required for 100 cm3 of water initially at 20C, 1 bar, if the piston is pulled until the volume is 1 liter. Assume that the temperature is constant in this process, and the pressure outside is 1 bar.

2) I am building a compressed-air rocket starting from a one-liter soda bottle half-filled with water, the other half filled with compressed air from a bicycle pump, to which I attach a nozzle with a 2 cm2 final cross-section. When the nozzle is opened, a water jet comes out due to the air pressure, which produces thrust. Calculate the minimum initial air pressure necessary to achieve lift-off as soon as the nozzle opens, given that the instantaneous thrust is the product of the outgoing mass flow rate and the water jet velocity. Initial temperature is 20C. Neglect the weight of the bottle itself. Assume air pressure and temperature inside the bottle to be nearly constant for a few seconds

Instructions
Website Creation: The Shaping of a Website

Please complete the following labs within Toolwire:

Part A Writing the Text Content of Your Website

As you continue building your website, remember to keep your goals and objectives in mind. Taking what you have learned within this and previous units, begin finding and creating specific content to include in your website. Also, refer back to Unit I for guidelines on writing for the web.

Upload the revised website plan presentation and the revised HTML and CSS pages for grading. Be sure to keep in mind that your website should be accessible to all users.

Part B Typography on a Website

After you have chosen the font or fonts you want to use for your web content, upload your revised website plan presentation and the CSS file with the updated fonts applied. Be sure to keep in mind that your website should be accessible to all users.

Part C Creating and Selecting Images for Your Website

After you have placed your images in your HTML files and added the new style to your CSS files, upload the HTML and CSS files for grading. You can upload as individual files or in a ZIP file. Be sure to keep in mind that your website should be accessible to all users. If you have questions, please reach out to the instructor for help.

Problem Solving (Show your work):
9)  What is the symbolic expression for the equilibrium constant for the reaction:
2 C2H6(g) + 7 O2(g) 4 CO2(g) + 6 H2O(g)?

10)  What is the gas phase chemical reaction that corresponds to the equilibrium constant expression shown below?

11)  Consider the reaction: N2(g) + O2(g) 2 NO(g). If [N2] = 0.520 M, [O2] = 0.0662 M, and [NO] = 0.00956 at equilibrium, calculate the value of K and describe the physical/chemical interpretation of this K value.
