Ethanol 1C2H5OH2 melts at -114 C and boils at 78 C. The
Chapter , Problem 11.45(choose chapter or problem)
Ethanol 1C2H5OH2 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 and 2.3 J>g@K, respectively. (a) How much heat is required to convert 42.0 g of ethanol at 35 C to the vapor phase at 78 C? (b) How much heat is required to convert the same amount of ethanol at -155 C to the vapor phase at 78 C?
