    Q = 2647 J

    Explanation:

    Specific heat capacity is the amount of energy required by one Kg of a substance to raise its temperature by 1 °C.

    In thermodynamics the equation used is as follow,

    Q = m Cp ΔT

    Where;

    Q = Heat = ?

    m = mass = 660 g

    Cp = Specific Heat Capacity = 0.3850 J. g⁻¹.°C⁻¹

    ΔT = Change in Temperature = 23.35 °C - 12.93 °C = 10.42 °C

    Putting values in eq. 1,

    Q = 660 g * 0.3850 J. g⁻¹.°C⁻¹ * 10.42 °C

    Q = 2647 J
