Vapour is a mixture of two or more different phases at room temperature, these phases are liquid and gaseous phase. Gas usually contains a single thermodynamic state at room temperature.
Vapour has a definite shape of the gaseous particles when observed under a microscope. Gas does not a definite shape when it is observed under a microscope.
Vapour consists of random molecules and atoms moving randomly about. Gas also consists of random molecules and atoms moving about randomly.
Vapour is not a state of matter, unlike gases. Gases are a state of matter.
Vapours of water are around us all the time at temperatures below the boiling point of water. Gases are usually formed above its critical temperature, but below critical pressure.
