Ans is "B" Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation.[1] As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets

Ans 3:

Class : Class 4
