Calorimetry is the process of measuring the heat associated with a change in a state variable. These state variables typically include temperature, pressure, and volume, though others may be included depending on the state being described.



When the variation in temperature relative to the heat supplied or extracted is measured, it is referred to as heat capacity. In the case of a gas, the heat capacity is influenced by the other state variables. Therefore, heat capacity is defined and measured at constant volume or constant pressure.
