Heat Capacity depends on the way the heat is 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 which result in different values of heat capacity:
Both p and are proportional to the the amount of the matter chemical substance involved in a Heat Transferheat transfer process and as such are not the material properties.
The ratio is called a Heat Capacity Ratio (γ) or Adiabatic Index (γ) or Isentropic expansion factor (κ) and is a material property.
Based on Mayer's relation the Isobaric heat capacity is always greater than Isochoric heat capacity:

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

Overall, there are totally six different intensive physical properties related to heat capacity:
