Changes in state are called phase changes. a phase change is a change from one physical state (gas, liquid, or solid) to another. the amount of energy necessary to melt 1 mole of any solid is called its enthalpy of fusion. the amount of energy necessary to vaporize 1 g of any substance is called its enthalpy of vaporization. the enthalpy of fusion of solid sodium is 2.60 kj/mol. calculate the energy required to melt 43.6 g of solid sodium.
