Definition

quotient of specific heat capacity at constant pressure and specific heat capacity at constant volume:

γ = \frac{c_{p}}{c_{V}}

where $c_{p}$ is specific heat capacity at constant pressure (specific heat capacity at constant pressure) and $c_{V}$ is specific heat capacity at constant volume (specific heat capacity at constant volume)

quotient de la capacité thermique massique à pression constante par la capacité thermique massique à volume constant:

γ = \frac{c_{p}}{c_{V}}

où $c_{p}$ est la capacité thermique massique à pression constante (specific heat capacity at constant pressure) et $c_{V}$ est la capacité thermique massique à volume constant (specific heat capacity at constant volume)

Notes

This quantity can also be expressed by

γ = \frac{C_{p}}{C_{V}}

where $C_{p}$ is heat capacity at constant pressure and $C_{V}$ is heat capacity at constant volume.

Cette grandeur peut également être exprimée par

γ = \frac{C_{p}}{C_{V}}

où $C_{p}$ est la capacité thermique à pression constante et $C_{V}$ est la capacité thermique à volume constant.
