    Answer:

    Heat required to heat the given amount of water is

    Q = 3.47 \times 10^7 J

    Explanation:

    As we know that heat required to raise the temperature of water is given as

    Q = ms\Delta T

    here we have

    m = 105 kg

    s = 4180 J/kg C

    now we have

    \Delta T = 99 - 20

    now we have

    Q = 105 (4180)(99 - 20)

    Q = 3.47 \times 10^7 J
