Mark me brainliests . Hope it helps
Explanation:
On blowing air from the mouth on the mirror, the mirror becomes moist. The air blown from mouth is hot and the mirror is cold. The hot air that we breathe out contains water vapors which turn into tiny droplets of water when it comes in contact with the colder mirror.
