Calculate the amount of energy (in kJ) necessary to convert 257g of liquid water from 0C to water vapor at 162C. The molar heat of vaporization of water is 40.79 kJ/mol. The specific head of water is 4.184 J/gC, and for steam is 1.99 J/gC. (Assume that specific heat values do not change over the range of temperatures in the problem.)
