SUMMARY
The discussion centers on understanding the functional dependency of entropy as presented in Kittel & Kroemer's "Thermal Physics." The author highlights specific pages (66-67, 43) where the text assumes entropy's dependency on energy (U) and volume (V) for a fixed number of particles (N). Key points include the assertion that the number of states, and thus entropy, is a function of U and V, while also acknowledging that entropy may depend on additional independent variables under certain conditions. The author expresses confusion regarding the derivation of these relationships and the assumption of constant entropy during interdependent changes in U and V.
PREREQUISITES
