Problem 32P Find an expression for the entropy of the two-dimensional ideal gas considered in below Problem. Express your result in terms of U, A, and N. Problem: Consider an ideal monatomic gas that lives in a two-dimensional universe (flatland), occupying an area A instead of a volume V. By followi

In Chapter 4 (at the end of Section 4.7) I claimed that, for a system with one degree of freedom, positions of stable equilibrium "normally" correspond to minima of the potential energy U (q). Using Lagrangian mechanics, you can now prove this claim. (a) Consider a one-degree system of N particles wi
