Calculate the amount of energy (in kJ) necessary to convert 517 g of liquid water from 0° C to water vapor at 177°C. The molar heat of vaporization (Hvap) of water is 40.79 kJ/mol. The specific heat for water is 4.184 J/g ·°C, and for steam is 1.99 J/g ·°C. (Assume that the specific heat values do not change over the range of temperatures in the problem.) |
