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} |
| Symbol | Dimension | SI units | Oil metric units | Oil field units |
|---|---|---|---|---|
| L2 T−2 Θ−1 | J/(kg⋅K) | J/(kg⋅K) |
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 capacity | Isochoric specific heat capacity |
|---|---|
Both and
are characterising the properties of matter and properly tabulated for the vast majority of materials.
Specific Heat Capacity relates to Volumetric Heat Capacity 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 relates to Volumetric Heat Capacity
.
The other confusion is made between
Physics / Thermodynamics / Thermodynamic process / Heat Transfer
