Amount of heat required to change the temperature of one unit of mass by one unit of temperature:

c_m = \frac{\delta Q}{\delta m \cdot \delta T}

c_m

 BTU/(lbm°F)


Specific 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 specific heat capacityIsochoric specific heat capacity

c_{mp}

c_{mV}


Both c_{mp} and c_{mV} are characterising the properties of matter and properly tabulated for the vast majority of materials.


Specific Heat Capacity relates to Volumetric Heat Capacity  c_v and density of the matter  \rho as:

(1) 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  c_v and Volumetric Heat Capacity  c_v.

The other confusion is made between Volumetric Heat Capacity  c_v and Isohoric Heat Capacity c_V.
