Ethanol melts at -114°C and boils at 78°C. The enthalpy of fusion of methanol is 5.02 kJ/mol, and is enthalpy of vaporization is 38.56 kJ/mol. The specific heat of solid and liquid ethanol are 0.97 and 2,3 J/g-K respectively. A) How much heat is required to convert 26.0 g of ethanol at 25°C to the vapor phase at 78°C. B) How much heat is required to convert the same amount of ethanol at -150°C to the vapor phase at 78°C.
