heat capacity n.
The amount of heat required to raise the temperature of one mole or one gram of a substance by one degree Celsius without change of phase. Also called thermal capacity.
| heat capacity
The ratio of the heat energy absorbed by a substance to its increase in temperature. Heat capacity is also called thermal capacity. ◇ The specific heat or specific heat capacity of a substance is the heat capacity per unit mass, usually measured in joules per kilogram per degree Kelvin. See also latent heat, thermodynamics. |
