Specific Heat Capacity depends on the way the heat is transferred and as such is not a material property.


The two major heat transfer processes are isobaric and isohoric which define:

Specific Heat Capacity 

LaTeX Math Inline
bodyc_m
 relates to Volumetric Heat Capacity

bodyc_v
 and density of the matter

body\rho
 as:

c_m =  \rho \cdot c_v


In many technical papers the "m" or "v" index is omitted which leads to confusion between  Specific Heat Capacity 

LaTeX Math Inline
bodyc_m
and Volumetric Heat Capacity 
LaTeX Math Inline
bodyc_v
.


For multiphase fluid in thermodynamic equilibrium the Specific Heat Capacity

 is:

c_m = \frac{\sum_\alpha s_\alpha \rho_\alpha c_{m \alpha}}{\sum_\alpha s_\alpha \rho_\alpha }
