in a glass of cold water, drops of water are observed outside the surface of glass . pls explain why???? because the condensation point of water vapour is 100 deg. C . Pls explain in refernce to this statemant!!!!(GIVE ME ANY OTHER REASON THAN DEW POINT)
This is called "condensation" on a glass, and "dew" if it occurs on grass / leaves. When the "dew point" of air is above the temperature of the surface of the glass, condensation will occur as humidity from the air releases heat into the glass and changes state from gas to liquid.

because the condensation point of vapour is 100C and the cold water in the glass is at some tempature less than 20C so vapour in the atmosphere cools down by the water in the glass so the vapour gets converted into drops and get stuck on the surface of the glass.
