Specific Heat Ratio γ for Liquids and Gases at Atmospheric Pressure

In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (cp) to heat capacity at constant volume (cv).

γ = c p c v
