Question
Dew and frost occur on a large scale in winters.

Answer

  • During winters when moisture-laden air near the earth’s surface comes in contact very cold objects, condensation of the vapour takes place.
  • They turn into very small water droplets. These water droplets get stick to the surface of the cold objects. This is called dew.
  • If the temperature of the air is less than 0°C, the water droplets stuck to the surfaces of cold objects freeze.
  • This frozen water droplet is called frost.
  • Thus dew and frost occur on a large scale in winters.
