    Answer:

    Q = 133.76 KJ

    Explanation:

    The amount of heat energy required to raise the temperature of the water can be calculated by the following formula:

    Q = mC\Delta T

    where,

    Q = Heat Energy Required = ?

    m = mass of water = 2 kg

    C = Specific Heat Capacity of Water = 4.18 KJ/kg°C

    ΔT = change in temperature = 26°C – 10°C = 16°C

    Therefore,

    Q = (2\ kg)(4.18\ KJ/kg.^oC)(16^oC)

    Q = 133.76 KJ
