A cylinder fitted with a movable piston contains liquid water in equilibrium with water vapour at . Which of the following operation results a decrease in the equilibrium vapour pressure at ?
Options:
Answer:
D
Solution:
Vapour pressure at a given temperature is an intensive property. It depends on the nature of the liquid and temperature. Dissolving a non-volatile solute (like salt) lowers the vapour pressure of the solvent (water) due to a decrease in the mole fraction of the solvent. This is a colligative property.
