A liquid is in equilibrium with its vapour at its boiling point. On the average, the molecules in the two phases have equal.

A liquid is equilibrium with its vapours in a sealed container at a fixed temperature. The volume of the container suddenly increased. What is the initial effect of the change on vapour pressure ?

A liquid is equilibrium with its vapours in a sealed container at a fixed temperature. The volume of the container suddenly increased. What happens when equilibrium is restored finally and what will be the final vapour pressure.

A liquid is equilibrium with its vapours in a sealed container at a fixed temperature. The volume of the container suddenly increased. How do rates of evaporations and condensation changes initially ?
