    The temperature of balloon that must be cooled to reduce its volume to 3.78l at constant pressure is calculated using the Charles law formula

    that is V1/T1 = V2/T2

    V1 = 4.39 L

    T1 = 44 + 273 = 317K

    v2 = 3.78L

    T2=?

    from the equation above T2 = V2 x T1/V1

    = 3.78 x317/4.39 = 272.95 k which is approximate 273 k

    T2 = 273 k or O c
