The heat of fusion of 36.9 g of an unknown metal that releases 2 .51 kJ of energy in freezing is to be calculated. Concept introduction: Heat energy is transferred to or from one substance during the change in state. Energy is required to melt a solid. Melting of a solid is an example of an exothermic change. The SI unit of energy is joule ( J ) . Fusion is the change of solid to liquid by addition of heat. The heat of fusion of a substance is the energy required to melt 1 g of the substance. It is denoted by the symbol ΔH fus .
