Question

the air we breathe out is warmer than air because of 1) heat is liberated 2) carbon dioxide is liberated 3) nitrogen is liberated 4)all the above​

Answer 1

Answer:

CARBON DIOXIDE IS LIBERATED

Explanation:

It is usually warmer, but not always. The temperature of the interior of your body is about 98-99 degrees Fahrenheit. So when you breathe in air that's cooler than that, the air is warmed by your lungs, and so it's warmer when it comes out. However, if the air you're breathing in is hotter than your body temperature, like say 105 degrees in the desert, the air will actually be cooled by your lungs, and will come out cooler than when it went in.

Answer 2

Answer:

carbon dioxide is liberated.
