$\textit{Volumetric Heat Capacity (VHC)}$, also termed $\textit{volume-specific heat capacity}$, describes the ability of a given volume of a substance to store internal energy while undergoing a given temperature change, but without undergoing a phase transition. It is different from specific heat capacity in that the VHC is a $\textit{per unit volume}$ measure of the relationship between thermal energy and temperature of a material, while the specific heat is a $\textit{per unit mass}$ measure (or occasionally per molar quantity of the material).
