    The new volume is 100mL

    Explanation:

    From the question given, we obtained the following information:

    V1 = 50mL

    T1 = 200K

    T2 = 400K

    V2 = ?

    V1 / T1 = V2 / T2

    50/200 = V2 / 400

    Cross multiply to express in linear form

    200 x V2 = 50 x 400

    Divide both side by 200

    V2 = (50 x 400) / 200

    V2 = 100mL

    The new volume is 100mL
