The difference between gas and vapour can be understood in the following ways:

1. State of Matter: A gas is one of the four fundamental states of matter, along with solids, liquids, and plasma. A vapour, on the other hand, is a substance in the gas phase at a temperature lower than its critical temperature, which means it can be condensed to a liquid by increasing the pressure without reducing the temperature.

2. Formation: Gases are formed when a substance is heated above its boiling point. Vapours are formed when a substance is heated below its boiling point.

3. Existence: Gases can exist at any temperature depending on the substance. Vapours exist only at temperatures below the critical temperature of the substance.

4. Condensation: Gases cannot be easily condensed into a liquid state by applying pressure alone. Vapours, however, can be easily condensed back into a liquid state by increasing the pressure or decreasing the temperature.

5. Examples: Oxygen, nitrogen, and carbon dioxide are examples of gases. Water vapour is an example of vapour.
