Amount of heat to be supplied to a given amount of a material to produce a unit change in its temperature:

 C =  \frac{\delta Q}{\delta T}

M L2 T−2 Θ−1J/KJ/K

 BTU/°R


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 resylt in different values of heat capacity:

Isobaric heat capacity (CP)

Isochoric heat capacity (CV)


Both
  and  are proportional to the amount of chemical substance involved in a heat transfer process and as such are not the material properties.


One can relate them to material properties through the known material mass  or a material volume  or material amount of substance :

Molar Heat Capacity Specific heat capacityVolumetric Heat Capacity
c = C/\nu
c_m = C/m
c_v = C/V


Overall, there are totally six different  heat capacity material measures:


Molar Heat Capacity Specific heat capacityVolumetric Heat Capacity
Isobaric (V= const)
Isochoric (P = const)
