    From Charle's law the volume of a fixed mass of a gas is directly proportional to the absolute temperature at constant pressure.

    Therefore';

    V1/T1=V2/T2

    Where; V1 = 2.40 l, T1 = 273 + 20 = 293 K, V2 = 4.80, and T2 = ?

    2.4/293 = 4.8/T2

    T2 = (4.8*293) / 2.4

    = 586 K or 313° C
