I don't know much about science or anatomy but I know that when I TALK, it's mostly hot air!   Qwaaakk!

Warm carbon dioxide

I am alive, hopefully, so my breath is warm.  I cool soup and coffee by moving it around the outside atmosphere.....

If you breathe out heavily but place your hand about a foot away from your mouth, you'll feel that it is about as cool as if you were blowing, and likewise, if you place your hand close to your mouth while blowing, you'll feel that it as warm as if you were breathing.

When I exhale it is air that is warmer than when I inhaled. Typically, when you find someone exhuding a lot of hot air, it is from the heat build up in their jaws due to never shutting up. Well, maybe not really. But in life, you'll usually find a lot of hot air coming from people who never shut up. They are easy to spot...the few moments when they're not talking, they usually have one of their feet in their mouth.

Hey! Did you read my response? Are you talkin' about me? Are ya' huh? Are ya'?

...never mind...don't tell me... :(

I think that your breath is cooler than the hot stuff you blow on to cool it, and warmer than the cold stuff you blow on to warm it.   In other words, your breath is just the right temperature. How it smells, well, there's a whole different kettle of fish.

And we KNOW how a kettle of fish smells! :(

IT .Depends the mood my Wife`s in.

Hey you! You weren't supposed to agree with me!

Neither. The temperature of the air you exhale is 1 0r 2 degrees lower than you body temperature which is neither cold or hot, it is WARM.

Okay then. :)

Hot, never cold unless immediately exhaled after or with a cube of ice in your mouth. Even if you blow hot or cold over an answer, the air is still hot :).
