1. Summarize the temperature dependence of thermal energy and specific heat of diatomic gases and solids with conduction electrons. (a) Please discuss, within the scope of your understanding, the results using the classical thermodynamics, classical statistics, and quantum statistics: do these results agree with each other? In what situation (what temperatures) do they agree? In what situation do they differ? Why? (b) Sketch the temperature dependence of the specific heat, marking characteristic temperatures on your plot. 2. review your HWs and final review sheet.
