Two containers, X and Y at 300K and 350K with water vapour pressures 22 mm and 40 mm respectively are connected, initially closed with a valve. If the valves opened,

Answer»

the FINAL pressure in each container is 31 mm
the final pressure in each container is 40 mm
Mass of `H_2O(L)` in X increases
Mass of `H_2O(l)` in Y decreases

Solution :Gas moves from Y to X to BALANCE pressure
In container `Y, l to G` to maintain same V.P
In container `X, g to l` to maintain same V.P .
