Explain the following : How can you relate the formation of water droplets on the outer surface of a bottle taken out of a refrigerator with formation of dew ?

Explanation

At a given temperature, there is a limit on how much water vapour the given volume of air to hold water vapour.
The temperature of a bottle kept in a refrigerator is lower than room temperature. Hence, when the bottle is taken out of the refrigerator, then temperature of the air surrounding the bottle is lowered. Therefore, the capacity of the air to hold water vapour becomes less. Hence, the excess water vapour condenses to from water droplets (like dew) ont he outer surface of the bottle.
