Question:

The normal melting point of copper is 1357 K, and ΔfusH of Cu is 13.05 kJ mol-1

(a) How much heat, in kilojoules, is evolved when a 3.78 kg sample of molten Cu freezes?

(b) How much heat, in kilojoules, must be absorbed at 1357 K to melt a bar of copper that is 15 cm x 12 cm? (Assume d = 8.92 g/cm3 for Cu.)
