Question:
Air containing 20.0mole% water vapor at an initial pressure of 1 atm absolute is cooled in a 1-liter sealed vessel from 200°C to 15°C.
(a) What is the pressure in the vessel at the end of the process’ (Him: The partial pressure of air in the system can be determined from the expression Pair = nair RT/V and P = Pair + PH2O. You may neglect the volume of the liquid water condensed, but you must show that condensation occurs.)
(b) What is the mole fraction of water in the gas phase at the end of the process?
(c) How much water (grams) condenses?
Step by Step Answer:

In this video, the concept of pressure has been explained. The bottle is filled up with water, remove the pipe, and now you can see the clear flow of water from the holes due to liquid pressure.You can see that the second layer is holding the weight of the first layer and the third layer holding the weight of both upper layers, that’s why liquid flows out wider from the third as compared to the first two.At the first hole, water doesn’t roll along the walls; it flows out at an angle.At the second hole, you’ll see that the water flows out at a wider angle as compared to the first hole.At the third hole, we can see that the flow of water is much wider/greater than the other holes.This proves that the pressure at the bottom of the bottle is much more than the pressure at the top layers. P = ????gh
