  • Q = m * c * dT

    m = 10 kg

    dT = 15 - 0 = 15 C

    c1 = 3.36 * 10^5 J/kg

    c2 = 4200 J/(kg C)

    First, figure out the energy required to melt 10kg of ice

    10 kg * 3.36 * 10^5 J/kg = 3.36 * 10^6 Joules

    Now figure out the energy required to heat the water by 15 degrees Celsius

    10 kg * 4200 J/(kg C)  *  15 C =>

    63000 Joules

    Altogether you have:

    3360000 + 63000 Joules =>

    3423000 Joules
