Question

2 kg of water at 5 celsius is added to ice at 0 celsius. The ice and water make up a closed system. Calculate how much of the ice melts

Answer 1

the sum of heats gained is zero (remember one of those has heat lost).

Heat gained by ice+heat gained by water=0
Hv*massicemelted+masswater*Cwater*(0-5)=0
solve for massicemelted.
