Full Answer

The Engineering Toolbox states that heat capacity is an extensive property, which means it is determined by the extent or size of the physical system under investigation. According to the site, the heat capacity of most systems is not a constant. Instead, the variables of the thermodynamic system under study determine the heat capacity value. Temperature itself dictates the measurement as well as the volume and pressure of the system, as explained by the Physics Classroom.
