When you exhale on a cold day, the air that goes out is saturated and the temperature of the air you exhale is warmer than the surrounding air. The water vapor in your breath condenses into many tiny droplets of liquid water and ice that you can see in the air as a cloud. It looks pretty similar to fog. Another reason you see your breath is due to the rapid change in dew point that the moisture you exhale creates in the surrounding air.

Keep in mind that every breath we take in. We all know that the main gas we breath out is carbon dioxide but we also breath out a little bit of oxygen as well as water vapor too.

Find a small mirror and put it in the refrigerator for an hour or so to make sure it's really cold. When you're ready, take out the mirror and get ready to breathe on it. First, take a few deep breaths and notice that you can't see your breath in the warm air around you. Then, breathe onto the mirror. Do you see how the mirror fogs up when you breathe on it? This occurs because the cold mirror cools the air right around it, which causes your warm breath to condense on the mirror as it hits the cold air.
