Heat capacity ratio

The heat capacity ratio gives the specific heat at constant pressure divided by the specific heat at constant volume for a substance. It is used in adiabatic processes and the speed of sound in gases.

\gamma = \frac{c_p}{c_V}

What the symbols mean

heat capacity ratio (dimensionless)
specific heat capacity at constant pressure (J/(kg\cdot K))
specific heat capacity at constant volume (J/(kg\cdot K))
