Diamond specific heat
WebJan 30, 2024 · For ordinary solids at or above room temperature, the molar heat capacity is approximately the same ( Dulong and Petit's law ), three times the gas constant, about 25 J/K. It is because the sum of potential and kinetic energy per atom is 3 k B T in the harmonic approximation. Hydrogen in water or ice is a bit different.
