how much heat required to convert ethanol in solid state to liquid state
Ethanol (C2H5OH) melts at -114 °C and boils at 78 °C. Its density is 0.789 g/mL. 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 J/g-°C and 2.3 J/g-°C, respectively. How much heat (in kJ) is required to convert 25.0 g of ethanol at 25 °C to the vapor phase at 78 °C? Enter your answer with the correct number of significant figures, and DO NOT include units.
