A chemistry student needs to determine the conditions at which a pure substance will change from solid to liquid phase. The substance in question has a melting point of 120 °C and a heat of fusion of 35 kJ/mol. How much heat is required to melt 100 grams of the substance at its melting point? And, what is the temperature at which the substance will start to solidify if the ambient pressure is 1 atm and the substance has cooled from its liquid phase at 150 °C to its solid phase?
