It can be calculated at constant volume by taking the partial derivative of the energy per mole of a substance with respect to temperature, which is key to the empirical observations of the Law of Dulong and Petit.
In 1912, Von Kármám and Born showed that the propagation of elastic waves through a solid causes this value to deviate from what Einstein's model predicted it would be, and Debye postulated that at low temperatures, it is equal to 234 times the molar gas constant times the quantity temperature divided by the Debye characteristic cubed.

For 10 points, name this quantity often measured in joules per gram-kelvin, defined as the amount of heat required to increase the temperature of a unit mass of a substance by a unit amount.
