Question

Differentiate between gas and vapour minimum 9 points .

Answer 1

gas

1.Agas refers to a substance that has a single defined thermodynamic state at room temperature 
2.steam would be a vapor because at room temperature, it would be water, which is a liquid.
3. gas iis formed at or above the boiling point of a liquid and a vapuor is formed below the boiling point of a liquid

vapour

1.vaporrefers to a substance that is a mixture of two phases at room temperature, namely gaseous and liquid phase.
2.vapor is a gaseous substance at a temperature when it ordinarily should be a liquid or a gas.
3.vapour particles are in a random motion, colliding .

hope this helps you

The Internet tells….

A gas refers to a substance that has a single defined thermodynamic state at room temperature whereas a vapor refers to a substance that is a mixture of two phases at room temperature, namely gaseous and liquid phase.

In simple terms , we can point out three differences:

A vapour has undergone a phase change while a gas did not. For example, nitrogen is gas in room temperature, but water is liquid. When water is heated, it undergoes a phase change and water vapour forms.Gas is a state of matter while vapour is not.A gas is a substance above its critical temperature but below its critical pressure, while a vapor is a substance above its boiling point temperature.
