Physics 78, [rcture Section 3, Fall 2010. Final Examination, @A. Zettl. Each of the 8 problerns is worth 20 points. Show all work. Three sheet of notes 8-1/2" x I ]. " (all 6 sides) allowed. Good luck. 1.

The "corner" volumes V1,V2,V., and Vo are also known, and identified below. a) _ _lnqpad of plottilg the_cycle in th" usual w3y on a P-V diagram (as shown below), plot the cycle on 1n SiI diagram, -with S on the vertical axis and T on the horizonlal axis. Explicifly identify S and T at the four "corners" ofthe cycle. b) Determine the net area enclosed correspond to? by the closed S-T curve. What physical quantity does this area yr'**{ 2. The temperature-dependent specific heat of a metal can usually be expressed as C(I) = AT + BT . The units of C are Joules/(Kelvin Kilogram), and A and B are positive (temperature-independent) constants. The "A" term represents the contribution to the specific heat from free electrons in the metal, while the uBu term represents the contribution to the specific heat from thermally-induced vibrations of the atomic cores.

### What students are saying

• 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.
