Expert Answer

Activity:

Take out a bottle of  soft drink from the refrigerator and place it on the table.

Observe for few minutes.

You will see small drops of water appearing on the outer surface of the bottle.

This is because water vapour present in the air condenses and forms small drops of water.

This activity proves that air contains water vapour.
