Question

A 0.106 kg ice cube is taken out of a freezer with temperature -16°C. It is then added to a glass of water with mass 0.25 kg. The water initially has a temperature of 24.2 °C. Assume no heat is added or lost to the surroundings.

Calculate the amount heat required to completely melt the ice when it starts at -16°C. (Assume the specific heat of ice is 2100 J/kg*°C and the latent heat of fusion of ice is 333,700 J/kg.)
