Description
In complex thermal systems in which the heat capacity varies with temperature, such as a typical Debye solid like silicon, the effective number of active degrees of freedom at any temperature can be defined from the internal energy in combination with equipartition. This allows for a conceptual picture of thermal equilibrium as well as elucidation of the link between the Boltzmann and thermodynamic entropies. It is shown that, in general, thermodynamic entropy is not the same as the Boltzmann entropy but there are clear circumstances under which they are identical. The instructional benefits of this approach are emphasized.
