Question
A cylinder fitted with a movable piston contains liquid water in equilibrium with water vapour at 25°C. Which of the following operation(s) results in a decrease in the equilibrium vapour pressure at 25°C?
Options
A.Moving the piston downward for a short distance.
B.Removing small amount of vapour.
C.Removing a small amount of liquid water.
D.Dissolving some salt in the water.
Solution
At constant temperature, the vapour pressure may be changed by changing the composition.
