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
