[QUOTE="Lord Jestocost, post: 6008204, member: 638573"] The heat capacity of a single harmonic oscillator is always [B][I]k[/I][/B][SUB][B]B[/B][/SUB] in the high temperature limit. In case you have a solid composed of [I]N[/I] atoms, you will thus always get 3[I]N[B]k[/B][/I][SUB][B]B[/B][/SUB] in the high temperature limit, even if you assume a certain distribution of 3[I]N[/I] normal modes of vibration where each has its own frequency.
