    Based upon the ideal gas law: PV=nRT, we can derive the following for the effects of changes in temperature (K) on volume (L).

    V1/T1 = V2/T2

    V2 = T2V1/T1

    V2 = (42) (5.4) / 15 = 226.8/15 = 15.12

    So the final volume will be 15.1 L, which makes sense because gases expand with increases in temperature.
