Heat Capacity of Blackbody
In Mathematical Physics of Blackbody Radiation I derive an expression for the heat capacity C(T) of a blackbody in the form of a forced damped wave equation as function of temperature T, of the form
with c a constant, thus with a linear dependence on T. This fits pretty well with observations for several solid metals for temperatures T smaller than 200 K, and for diamond up to 500 K, as shown above.
I do not use statistical mechanics but instead a concept of finite precision computation.
