Heya,

Take a chilled soft drink bottle and keep it on a table. After some time you will notice water droplets on the outer surface of the bottle.

This happens because when the water vapour in the air comes in contact with chilled surface of the soft drink bottle, it condenses to form water droplets.

#hope this helps...

place a cold bottle outside , you will see few drop of water at the surface of the bottle. this phenomena shows that the water vapour is present in the air because when a gaseous substance get low temperature , it turns into the liquid state.
