Answer:

D) melt 1 g of ice

Explanation:

Heat of fusion is the energy required to change the state of a substance from solid state to liquid state at a constant pressure.

Heat of fusion of water occurs when solid ice acquires energy and turn into liquid water through a process known as melting.

Thus, if the heat of fusion of water is 79.5 cal/g, it means 79.5 cal of energy are required to melt 1 g of ice.

D) melt 1 g of ice
