It is known that the vapor pressure of pure water at 77C is 41.847kPa, and at 100C is 101.325kPa
(a) Derive the relationship of vapor pressure to the temperature
(b) Calculate the vaporization enthalpy of water
(c) What is the vapor pressure of water at 140 ℃?
(d) 1 mol superheated water, vaporized water vapor at 141℃, 100kPa external pressure, calculate the △ S of this process.
