Question

Why does window paint become damp if one breathes on it answer in short?

Answer 1

Answer:

The moisture contained in our breath condenses upon contact with the glass pane of a window causing it to look foggy and damp.

Explanation:

The glass pane is cooler than our breath which also contains water molecules. When our warm breath hits the cool surface of the glass, it causes condensation and the water molecules are converted to tiny liquid droplets. This appears as a foggy layer on the glass.
