Web26 sep. 2024 · The Wikipedia article states the Dulong-Petit law as follows: c = 3 R M c is specific heat capacity [ J k g K] and R the gas constant. M is the molar mass in [g/mole], and "grams per mole" makes us think of a number of moles of a substance, as were it a molecular material. In crystal structures there is no such thing as a "mole" of the substance. WebThe heat capacities of many solid elements were shown to be closely related to their atomic weights by the French scientists Pierre-Louis Dulong and Alexis-Thérèse Petit in 1819.
