Enter your answer in the provided box. Calculate the amount of energy (in kJ ) necessary to convert 537g of liquid water from 0C to water vapor at 162C. The molar heat of vaporization (Hvap) of water is 40.79kJ/mol. The specific heat for water is 4.184J/gC, and for steam is 1.99J/gC. (Assume that the specific heat values do not change over the range of temperatures in the problem.) Enter your answer in the provided box. The vapor pressure of a liquid doubles when the temperature is raised from 8.0101C to 88C. At what temperature will the vapor pressure be four times the value at 8.0101C ? The molar heats of fusion and sublimation of lead are 4.77 and 182.8kJ/mol, respectively. Estimate the molar heat of vaporization of molten lead. Hvaporization=molkJ
