Question

On chilly days when we breath out on a glass or a window , the glass steams up. Why do you think this happens?

Answer 1

Explanation:

this is because the heat generated by out body comes out and condenses on the glass window and forms little droplets of water

Answer 2

It is so because the warm air coming out from our mouth is warm and when it comes in contact with the cold glass surface the water vapour condenses to form little droplets of water on the surface of the glass.
