Ethanol (C2H5OH) melts at -114 oC and boils at 78 oC. The enthalpy of fusion of ethanol is 5.02 kJ/mol, and its enthalpy of vaporization is 38.56 kJ/mol. The specific heat capacity of solid and liquid ethanol are 0.97 and 2.3 J/g-K, respectively.
How much heat is required to convert 42.0 g of ethanol at 35 oC to the vapor phase at 78 oC?
How much heat is required to convert 42.0 g of ethanol at -155 oC to the vapor phase at 78 oC?
