Aluminum metal is a solid at room temperature. When heated, it can turn into liquid, then gas at the end. The normal melting point of aluminum is 655 0C and the normal boiling point is 2425 0C. The molar heat capacities of aluminum solid, aluminum liquid and aluminum gas are 24.35, 24.21, and 21.38 J/mol-K, respectively. The enthalpy of fusion of aluminum is 376 J/g, and its enthalpy of vaporization is 11.370 kJ/g. How much heat is required to raise the temperature of 42.0 gram of aluminum from 21.57 0C to 710.34 0C? __________ kJ
