Ethanol melts at -114.0 ?C. The enthalpy of fusion is 5.02 kJ/mol and the enthalpy of vaporization is 38.6 kJ/mol. The specific heats of solid and liquid ethanol are 0.970 J/g?K and 2.30 J/g?K, respectively.
How much heat is needed to convert 55.5g of solid ethanol at -182.5?C to liquid ethanol at -50.0?C ?
