Heat Capacity depends on the way the heat is transferred and as such is not a table property of the matter.


The two major heat transfer processes are isobaric and isohoric which define:

Isobaric heat capacity

Isochoric heat capacity

Both

 and

bodyC_V
 are proportional to the amount of the matter involved in a Heat Transfer process and as such are not material properties.


One can relate them to material properties through the known material mass
