Question

why do we see water droplets on the outer surface of a glass containing ice-cold water?!. please tell the answer fast

Answer 1

Sometimes we see water droplets on the outer surface of the glass containing ice-cold water this isbecause 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 seeas water droplets

or
When water vapor in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That's condensation
