Answer
Cold air causes the warmth moisture in our breath to condense right into tiny droplets of water that show up like a small, misty cloud.

Many civilization think seeing her breath has every little thing to do with temperature, yet the spectacle has actually just as much to perform with the quantity of humidity in the atmosphere.
Because our body contain virtually 70% water, the waiting in our lung is almost fully saturated through water vapor (water in gas form) and also is the exact same temperature as our bodies (98.6oF). Cold wait cannot hold as much moisture as heat air. So when one exhales a warm, saturation breath top top a cold day the cold air promptly lowers the temperature of ours breath, whereupon the mix briefly will dew point. At dew point, air deserve to no longer organize water vapor; when air is cooled past dew suggest water vapor turns to liquid form, the physical procedure known together condensation. That is this liquid type of your breath – minuscule droplets that water – that creates the fleeting, misty cloud we see once breathing in cold weather.

Seeing her breath requires just the right mix of temperature and humidity. Though it is pretty typical to check out your breath in cold weather (usually listed below 45oF), the next time you have fun making breath clouds, you’ll know it’s because of the exact scientific research of atmospheric moisture and also temperature.
