Specific Heat
</dt>
The ratio of the heat absorbed (or
released) by unit mass of a system to the corresponding temperature
rise (or fall). If this ratio varies with temperature, it must be defined as a
differential quotient dQ/dT, where dQ is the infinitesimal
increment of heat per unit mass and dT is the infinitesimal increment
of temperature.

For gases the thermodynamic process must be specified; two specific
heats are defined, one being the specific heat in a constant-pressure process
In a perfect gas these are, by definition, constants with respect to temperature, and the difference of the specific heat at constant pressure and the specific heat at constant volume is equal to the
gas constant:]]
