8) AHvap is a way to measure intermolecular forces quantitatively. Calculate the amount of energy (in kilojoules) needed to cool 646 g of water vapor from 150oC to -17 oC. Assume that the specific heat of water is 4.184 J/g oC over the entire liquid range and the specific heat of steam is 1.99 J/g oC. The AHvap for water is 40.79 kJ/mol. The AHfus = 6.01 kJ/ mol.
