Water vapor in your breath condenses when it contacts cold air. (It looks like steam.)
by the temperature outside
because they sleep...in the winter and show in the summer
Breath normally only appears when it's cold, although you can see the effects of breath by breathing on a mirror or window.
well there are evergreen trees and they give of oxygen too
Most commonly falling leaves.
When you breath smells, you have a condition known as halitosis.
"Quiet winter night, frosty breath dances with stars, loneliness whispers."
Well this happens due to the heat from your breath.
I see my breath, it's just that cold It's so cold i see it hold in the air... ?? i ain't such a gr8 poet :)
Not just human breath is visible in winter, that happens to all warmblooded organisms. What you are seeing is the moisture in your breath evaporating into the air. It doesn't happen in summer because it is generally not cold enough for the process to happen.
It is NOT smoke, it is steam. It is your warm breath freezing in the cold winter air.
Because farts dont have a high H20 level, and your breath does. It's the water that you see condensating, not your actual breath. Also, farts are alot warmer and thus less prone to condensate.
