1 HW 13 Tips; PHY 131 Sect. 10, 11, 15; Fall 2010 Prof. Pascuzzi HW 13 covers Temperature, Ideal Gas Law & Linear Thermal Expansion (Ch.17, 18) Problem 17.3 Part A). This is a very basic conversion from Fahrenheit temperature to Celsius temperature using the relationship . Just plug in and solve. Part B). Use the same equation between the temperatures ( ) but now solve it for T F and just plug in and solve. This is problem #3 in Ch. 17, pg. 471. Problem 17.10 Part A). This problem deals with linear thermal expansion using this relationship between the change of length ( ) and the actual original length of the object ( ) when subjected to a temperature change ; . Use your basic knowledge of percents to think about how to relate 1.1% to and then just plug in appropriate values and solve for T f . Note you have to look up the expansion coefficient of brass. This is problem #10 in Ch. 17, pg. 472. Problem 17.31 Part A). This is a straightforward and common application of the ideal gas law to a before and after situation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
