Answer 1

Hey Mate!!

The air we exhale has a higher carbon dioxide content and a lower oxygen content than the air we inhale (fresh air). (By volume, fresh air is 1% oxygen and 0.0 % carbon dioxide; exhaled air is 16% oxygen and 5% carbon dioxide).

When we exhale, the composition of the air remains almost the same as the air we inhale, only the percentage of carbon dioxide and oxygen changes. The amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide.

Hope this helps you!!
