Expert Answer:

The term vapour is used to describe the state of a substance when it's gaseous phase is in equilibrium with it's liquid or solid phases, below it's boiling point. It is distinguished from the pure gas phase by the presence of the same substance in another state of matter. Hence when a liquid has completely evaporated, it is said that the system has been completely transformed to the gas phase.
