| Dulong and Petit's law |
The Dulong-Petit law, found in 1819 by Pierre Louis Dulong and Alexis Thérèse Petit, states the classical expression for the specific heat capacity of a crystal due to its lattice vibrations. The result is extremely simple: regardless of the nature of the crystal, the specific heat capacity is equal to 3R/M, where R is the gas constant and M is the molar mass. ...

the atomic heat capacity, the product of the atomic weight and the specific heat per gram, is constant for most elements; boron, carbon, and silicon are notable exceptions at normal temperatures.
