Heat Capacity = C

@wikipedia

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

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 result in different values of heat capacity:

Both  $//<![CDATA[ \begin{array}{l}C_P\end{array} //]]>$ and  $//<![CDATA[ \begin{array}{l}C_V\end{array} //]]>$ are proportional to the amount of chemical substance involved in a heat transfer process and as such are not the material properties.

The ratio  $//<![CDATA[ \begin{array}{l}\gamma = C_P/C_V\end{array} //]]>$ 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  $//<![CDATA[ \begin{array}{l}m\end{array} //]]>$ or a material volume  $//<![CDATA[ \begin{array}{l}V\end{array} //]]>$ or material amount of substance  $//<![CDATA[ \begin{array}{l}\nu\end{array} //]]>$:

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