Words: constant-volume process isometric process isovolumetric process isochoric process
Part of speech: n
Definition: a thermodynamic process during which the volume of the closed system undergoing such a process remains constant.
Example: In practice, a gas that receives heat in an isochoric process is a constant volume heating and at the same time it is a constant volume pressurization; a gas that looses heat in an isochoric process is a constant volume cooling and at the same time it is a constant volume depressurization.
