Question

Why do we see warer droplets on the outer surface of the glass containing ice cold water?

Answer 1

The water vapour present in the air, on coming in contact with the cold glass of water, loses energy and gets converted to a liquid state (gets condensed), which can be seen as tiny water droplets.

Answer 2

Sometimes we see water droplets on the outer surface of the glass containing ice-cold water this is because the water vapour presents in air, on coming in contact with the cold glass of water, loses energy and gets converted to liquid state, which we see as water droplets.
