6 Differences between Vapour and Gas
S.NO.  | Vapour  | Gas  | 
1.  | Vapour is a gas that is in a liquid or solid state at a temperature below its boiling point.  | Gas is a substance in the gaseous state at any temperature.  | 
2.  | Gas cannot condense to form a liquid under normal conditions.  | |
3.  | Vapour is dependent on temperature and pressure.  | Gas is not dependent on temperature and pressure.  | 
4.  | Vapour is typically denser than gas, as it is in a more condensed state.  | Lighter than vapours.  | 
5.  | Vapour is more compressible than gas due to its higher density.  | Less compressible.  | 
6.  | Vapour is a state of matter that exists between the liquid and gas states.  | Gas is a state of matter that exists on its own.  |
