Unformatted text preview: Homework #10 PHYS 404 Fall 2011 Deadline: Thursday, November 17, 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 35 points. Ch. 6 Boltzmann Statistics 1. Problem 6.14, 5 points. Barometric distribution from the Boltzmann factor. 2. Problem 6.18, 5 points. General formula for the rms deviation of energy. Directions to help you: First, prove the formula for E 2 written in the problem. The proof is similar to Problem 6.16, which was discussed in class. Then, proceed to proving the second formula written in the problem. To do this, you dont need to solve the two previous problems in detail. I give you the summary below. The root-mean-square deviation E of the energy E is defined as follows 2 E = ( E- E ) 2 = X s...
