hi mate here IS ur answer

A gas has one defined state at room temperature whereas a vapour is a substance that is in gaseous and liquid equilibrium at room temperature, at a given pressure. A gas can also refer to a single element of matter with its own unique physical and chemical properties, for example oxygen, nitrogen and neon

Difference between vapour & gas -

- Gases are normally present in gaseous state at room temperature while vapour is either liquid/solid phase at room temperature.

- Gases obey ideal gas equation while vapors don't.

- In gases evaporation is complete whereas in vapors evaporation is not completed.

- With change in temp & pressure gas remains in gaseous state. Vapour may condense/evaporate with change in conditions.
