Question

using mirror how will you prove that air we breathe out is having moisture? write in own words​

Answer 1

When we breathe out on a mirror, there appears a moisturised layer made of small water droplets.

The water vapour that we breathe out got condensed to form small water droplets.

Hence we can conclude that the air we breathe out contain moisture or water vapour.

Answer 2

Explanation:

The air which we are releasing has hot temperature and due to winters the mirror is having low temperature

So when the hot air comes in contact with cold glass ,the temp automatically gets lower and it evaporates on the surface of mirror
