1.	A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased. What is the initial effect of change on vapour pressure ?
Answer» Solution :`underset("Low pressure")(A_((l)))tounderset("High pressure")(A_((g))` If volume is INCREASED at constant temperature, pressure DECREASES, since, `p prop 1//V` at constant temperature. Decrease in pressure SHIFT the equilibrium in the direction of high pressure i.e. more vapours are formed HENCE vapour pressure INCREASES.
