When do we use Cp and Cv in thermodynamic equations? - Quora

WebCv is defined as the quantity of heat energy that a substance absorbs or releases (per unit mass) as a result of a change in temperature when no change in volume takes place. In other words, it is the amount of thermal energy that is exchanged between a system and its surroundings without any change in the volume of the system being transferred.
