Web3 rows · One of many remarkable properties of diamond is its unsurpassed thermal conductivity. With a ... 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.
