WebHeat capacities of solids Any theory used to calculate lattice vibration heat capacities of crystalline solids must explain two things: 1. Near room temperature, the heat capacity of most solids is around 3k per atom (the molar heat capacity for a solid consisting of n-atom molecules is ~3nR). This is the well-known Dulong and Petit law. 2.

WebTherefore, the total heat capacity per atom is C = 3 k B.
