Question

Using Our Breath

cold or warm? You may notice that the air you blow out is hot and
humid. This is because our body is hot inside and has a temperature of
98.40F
meaning of 98.40F​

Answer 1

Answer:

You can warm your hands by blowing on them because your breath is hotter than your skin (particularly on a cold day). By blowing, you transfer energy from inside your body to your hands by convection. Moist air, like your breath, carries a lot of energy so it warms things more quickly than dry air.
