With respect to the three quantities-pressurep p, density d and absolute temperature T- the gas equation can be written as

Temerature dependent equation can be written as :

An ideal gas equation can be written as P = rho R T/ M_0 where rho and M are resp.

An ideal gas equation can be written as P = rho R T/ M_0 where rho and M are resp.

Temperature dependent equation can be written as

The temperature of a hypothetical gas increases to sqrt(2) times when compressed adiabatically to half the volume. Its equation can be written as
