Homework #4 — PHYS 404 — Fall 2011 Deadline: Thursday, October 6, 2011, in class Professor Victor Yakovenko Office: 2115 Physics Web page: http://www2.physics.umd.edu/ ~ yakovenk/teaching/ Textbook: Daniel V. Schroeder, An Introduction to Thermal Physics Addison Wesley Longman, 2000, ISBN 0-201-38027-7 Do not forget to write your name and the homework number! Total score is 40 points. Ch. 2 The Second Law 1. Problem 2.26, 5 points. Multiplicity of the 2D ideal gas. 2. Problem 2.31, 10 points. Derive the Sackur-Tetrode equation. Additional question: Express the energy U per particle N in terms of the temperature T using the formula (1.23) with f = 3 (monoatomic gas): U/N = (3 / 2) kT . Rewrite the formula (2.49) for the entropy per particle s = S/N in terms of the temperature T , the concentration of particles n = N/V , and other parameters. Sketch the entropy S as a function of T . Estimate the temperature T * where S ( T ) formally becomes negative. Express T * in terms of n and the atomic mass m , and then in terms of a = 3 n , which is the typical distance between the atoms. The

### 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.
