c. The energy you create when you breathe
heats up the
mirror, causing water vapor
in
the air to condense
on it.
d. There is water in the air you breathe out
and it condenses on the mirror.



Answer :

Final answer:

Condensation of water vapor from warm, exhaled air creates the fog effect on a mirror when breathed upon.


Explanation:

Condensation occurs when warm, moist air cools, causing water vapor to transition into liquid water droplets. When you breathe out warm, moisture-laden air on a cold surface like a mirror, the sudden temperature change causes the water vapor to condense into tiny droplets, creating the 'fog' you see. This process is similar to how clouds form in the atmosphere.
