Problem- Ethanol, CH3CH2OH melts at 159 K and boils at 351 K. The heat of fusion is 5.02 kJ/mol and the heat of vaporization is 38.56 kJ/mol. The specific heats of solid, liquid and gaseous ethanol are 0.97, 2.3 and 1.9 J/g•K, respectively. How much heat must be added to a 115.5 g sample of solid ethanol initially at 77 K to raise the temperature to 300 K.
