NCERT VI Social Sciences

Take out a cold bottle of water from the refrigerator and keep it on the table. After some time, you will notice a puddle of water around it. Why?

Answer 1

As the bottle contains cold water its outer surface is cold. The air around us contains watervapour. When the cold surface of the bottle meets with the water vapour it condenses and small drops of water appear on the surface of the bottle and after some time water collects around it and we can notice a puddle around it .

Answer 2

It is due to condensation of water vapours present in air. The cold surface of the bottle cools the air around it, and the water vapour of the air condenses on its surface.
