Ethanol (C2H5OH) melts at?114°C and boils at 78°C. The enthalpy of fusion of ethanol is 5.02 kJ/mol, and its enthalpy of vaporization is 38.56 kJ/mol. The specific heats of solid and liquid ethanol are 0.97 J/g-K and 2.3 J/g-K

A.How much heat is required to convert 45.0 g of ethanol at 22°C to the vapor phase at 78°C?

B.How much heat is required to convert the same amount of ethanol at -144°C to the vapor phase at 78°C?
