sorry, this question is wrong therefore no answer for it from anwers. com thank u if any schools have selected this please say the teachers to cross out the question thank you
The composition of expired air in humans is usually: 17 % oxygen, 3. 5 % carbon dioxide, 79 % nitrogen, and temperature range of between 29 and 34 degrees Celsius, Moisture is usually a component of the expired air as well.
Because the body has used the oxygen in the air to oxidize the nutrients you eat, this process combines the oxygen that you inhaled with carbon which makes up part of the nutrients you eat to form a poisonous gas "carbon-dioxide" which is then transported back to the lungs and exhaled along with moisture.
CO2 makes up most of the exhaled air in vertebrates.
The typical composition of exhaled air is about 18% O2, 78% N2, and 4.0% CO2

The amount of moisture - water vapour, that air can carry without the water condensing - turning into droplets, depends on the temperature. Exhaled air has a fair bit of moisture in it that it has picked up from the lungs and the airways. If you exhale when it's warm, that moisture stays suspended in the air, and you don't see it. If you exhale when it's cold, the moisture condenses into tiny droplets, which you see as fog. Pretty much the same as when beads form on a cold glass or bottle or soda can. Or why a mirror steams over when you breathe on it.
Like any other fluid, as urine, sweat, moisture in your exhaled air, and part of your feces.
As the individual exhales through the HME, the filter picks up the moisture from that exhaled breath. That moisture is then picked up on the the next inhalation, thus humidifying that air.
Inhaled air is richer in oxygen than exhaled air.
yes it is the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) more
A drop in air temperature.
Yes. Actually higher than 100% most of the time ... which is why you can see your breath in the winter. (the moisture is condensing)
because your body is getting rid of moisture from the body when the gas exchange occurs in the lungs moisture is exhaled
When blowing on a fire it increase air flow. This in turn provides more oxygen which fires need to sustain themselves. In the case of candles, they are too small to handle the air flow.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
