Ethanol melts at 159K and boils at 351K. The enthalpy of fusion is 5.02 kJ/mol, the enthalpy of vaporization is 35.56 kJ/mol, and the molar mass is 46.07 g/mol. The specific heats of solid ethanol is 0.97 J/g-K, for liquid ethanol it is 2.3 J/g-K, and for gaseous ethanol it is 1.9 J/g-K. How much heat (kJ) is needed to convert 215 g of liquid ethanol at 160 K to gaseous ethanol at 713 K?
