Question

during cold Nights sometimes Dew is formed give reason​

Answer 1

Dew is made of liquid water that has condensed from some of the water vapor in the air. Dew occurs when objects cool. A common example of dew formation is when drops of liquid form on the glass of an ice-cold drink. Dew forms when the object, such as the glass, cools down to the dew point temperature

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. During a cold night, the temperature of air may fall to the dew point, or even below the dew point.

2. If the temperature falls below the dew point, the excess of water vapour in the air condenses on the surfaces of cold bodies and dew is formed.
