heat capacity




Also called thermal capacity, the amount of heat needed to raise the temperature of an object through 1°C, either at constant pressure or at constant volume and without inducing chemical changes or a change of phase. Numerically it is equal to the product of the mass of the object and its specific heat. Heat capacity is measured in joules per kilogram (SI units) or calories per gram.
