Question

difference between gas and vapour (8 point) ?

Answer 1

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. ... A vapour can co-exist with a liquid or solid when they are in equilibrium state.

Answer 2

DIFFERENCE BETWEEN GAS AND VAPOUR :-

GAS

1) A gas is state of matter .

2) Gas is formed by the process of boiling .

3) Gas is formed at or above 100 degree Celsius .

4) Gas has low density .

5) It remains as gas only in room temperature .

6) It molecules are separated .

7) The gases show the property of diffusion .

8) Gas are highly compressible .

VAPOUR

1) Vapour has about to experience phase change .

2) It is the result of boiling and evaporation .

3) It is measured by pressure of gas .

4) At the room temperature vapour can be solid or liquid.

5) Vapour is not a state of matter .
