Question

differentiate between gas and vapour

Answer 1

Hi there


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.


Thank You

Answer 2

Answer:

the two substances are very much different.

gas-

1.it is a state of matter.

2.it has experienced phase change.

3.it has low density.

4.it remains as gas only in room temperature.

5. its molecules are separated.

vapor-

1.it is a state of water between gas and liquid.

2.it has about to experience phase change.

3.it is the result of boiling and evaporation

4.it is measured by pressure of gas.

5.at room temperature. vapor can be solid or liquid.
