Lesson: Heat of Fusion

A bag of ice has a mass of 4.10 kg. The bag of ice is in a cooler that is taken on a picnic. All of the ice melts after 720.000 minutes of picnicking. The ice temperature at the start of the picnic is and the water temperature at the end of the picnic is also . Determine the average heating power received by the ice. Use a value of 333.55 J/g for the specific latent heat of fusion of water.

A package of frozen vegetables has a mass of 0.740 kg and is at a temperature of . Determine how much heating of the vegetables is required to thaw them. Use a value of 333.55 J/g for the specific latent heat of fusion of water.

A block of ice has a mass of 0.100 kg and an initial temperature of . A 0.100 kg mass of water that has a temperature of is poured onto the ice. Determine the equilibrium temperature of the ice and water, assuming that the temperature is reached sufficiently rapidly and that heat loss from the ice and water is negligible. Use a value of for the specific heat capacity of water, for that of ice, and 333.55 J/kg for the specific latent heat of fusion of water.
