The molar heat capacity of a chemical substance is the amount of energy that must be added, in the form of heat, to one mole of the substance in order to cause an increase of one unit in its temperature. Alternatively, it is the heat capacity of a sample of the substance divided by the number of moles of the sample; or also the specific heat capacity of the substance times its molar mass. The SI unit of specific heat is joule per kelvin per mole, J⋅mol−1⋅K−1.
