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} |

---|---|---|---|---|
C | M L2 T−2 Θ−1 | J/K | J/K |
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:
Both C_P and C_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
m or a material volume
V or material amount of substance

Overall, there are totally six different heat capacity material measures:
Molar Heat Capacity | Specific heat capacity | Volumetric Heat Capacity | |||||||
---|---|---|---|---|---|---|---|---|---|
Isobaric | Isobaric molar heat capacity
| Isobaric specific heat capacity
| Isobaric volumetric heat capacity

Isochoric | Isochoric molar heat capacity
| Isochoric specific heat capacity
| Isochoric volumetric heat capacity
