Heat capacity is an extensive property, i.e., it depends on the amount and size of the substance. A modified form of heat capacity (called specific heat capacity or simply specific heat) is commonly used in physics. Specific heat doesn’t vary with the amount of the substance and is, th...
InDulong–Petit law gram-atomic heat capacity (specific heat times atomic weight) of an element is a constant; that is, it is the same for all solid elements, about six calories per gram atom. The law was formulated (1819) on the basis of observations by the French chemist Pierre-Louis...
