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 38.56kJ/mol. The specific heats of solid, liquid and gaseous ethanol are 0.97, 2.3 and 1.9 J/g*K respectively. If 8.2 kJ of heat is added to a 27.0g sample of solid ethanol initially at 77 K, What will be the final temperature of the ethanol (in K)? ____ (answer), ___ (units)
