    Pressure of the gas P1 = 30.7 kpa

    When it doubled P2 = 61.4 kpa

    Temperature T1 = 0 = > T1 =. 0 + 273 = 273

    Temperature T2 = ?

    We have pressure temperature equation P1T1 = P2T2

    => T2 = P1T1 / P2 = (30.7 x 273) / 61.4 = 136.5

    So the temperature for doubling the pressure is 136.5.
