Answer:

Why is it that when you blow air out of your mouth with pursed lips, the air is cool to the touch, but when you exhale with your mouth wide open, the air is warm? asks Samir El-Sawaf, a student in Brookville.Have you ever found yourself "blowing hot and cold" on something (or someone)? You love the idea of a vacation in Florida (the beach! Disney World!). No, wait, you hate the idea (the bugs! the alligators!). Changing your mind seems easy. But adjusting the temperature of your breath, actually blowing hot and then cold? That seems downright impossible.
