    one can read wikipedia on "Adiabatic process", there are expressions involving both pressures, temperatures and gamma = 1.4 for air

    it depends upon the process.whether its isentropic or polytropic.If its isentropic then the formula wouls be

    sorry its gamma -1\gamma.t1 may be normal temp
