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

$\begin{array}{l}\displaystyle C = \frac{\delta Q}{\delta T}\end{array}$

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
$\begin{array}{l}C_p\end{array}$	$\begin{array}{l}C_V\end{array}$

Both $\begin{array}{l}C_p\end{array}$ and $\begin{array}{l}C_V\end{array}$ are proportional to the amount of the matter involved in a Heat Transfer process and as such are not table properties of the matter.

One can calculate them based on the mass of material $\begin{array}{l}m\end{array}$ or a volume of the material $\begin{array}{l}V\end{array}$ :

  
	(1)
	C_p= m \cdot c_{mp} = V \cdot c_{vp}

  
	(2)
	C_V= m \cdot c_{mV} = V \cdot c_{vV}

$\begin{array}{l}c_{mp}\end{array}$

Specific heat capacity under at constant pressure

$\begin{array}{l}c_{mV}\end{array}$

Specific heat capacity under at constant volume
