Air containing 20.0 mole% water vapor at an initial pressure of 1 atm absolute is cooled in a
1-liter sealed vessel from 200 C to 15 C.
What is the pressure in the vessel at the end of the process? ( The partial pressure of air in
the system can be determined from the expression and . You
may neglect the volume of the liquid water condensed, but you must show that condensation
occurs.)
What is the mole fraction of water in the gas phase at the end of the process?
How much water (grams) condenses?
