Question

how do you verify that air contains water vappur​

Answer 1

Answer:

We would observe that a large number of tiny drops of water appear on the outer surface of the steel tumbler. This happens because the air around the steel tumbler contains water vapour in it.

Take out a bottle of water(cold) from the refrigerator and place it on the table. 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.
