# Formula Heat capacity ratio Specific heat capacity

## Heat capacity ratio

Unit
Adiabatic exponent is defined as the quotient of heat capacity at constant pressure and heat capacity at constant volume. The adiabatic exponent can be used to find out how many atoms make up a gas molecule of a gas. Monatomic gas: $$\gamma ~=~ \frac{5}{3}$$.

## Specific heat capacity

Unit
Heat capacity (per mass) at constant pressure of the gas.

## Specific heat capacity

Unit
Heat capacity (per mass) with the volume of the gas kept constant.
