A gaseous substance that cannot be liquefied by the application of pressure alone.
A gaseous substance that is below its critical temperature, and can therefore be liquefied by pressure alone.
Description
Is a state of matter
Vapor is a substance in a gaseous state - at a condition where it is ordinarily liquid or solid.
States of Matter
One of the four fundamental states of matter, along with solid, liquid, and plasma.
Not a state of matter. Equilibrium between two states of water, i.e. gas and liquid or solid.
Natural State
At room temperature, the gas would still be a gas in its natural state.
At room temperature, the vapor’s natural state would either be solid or liquid.
Phase Change
In order to change the phase of a gas, one would need to change the temperature and the pressure.
Vapor can easily be changed to its natural state just by changing the pressure. The temperature need not be changed.
Physical Properties
Gases are easy to compress, they expand to fill their containers, and they occupy far more space than the liquids or solids. They do not have a definite shape when viewed under a microscope.
Vapor particles may have a definite shape when observed under a microscope. They are also easier to compress as they are constantly transitioning

Gas is a single well defined state at room temperature ..On the other hand ,a vapour is a state which co-exists with its liquid state at room temperature..
