Oxygen must be dissolved into water, the colder the water, the better (this is the opposite for dissolving solids, where the hotter the water/solvent the more you tend to dissolve in it). Hence by boiling water we eliminate most of the dissolved oxygen (and other gases), giving you all those bubbles as it boils.
In air however, it is free to merely float around and mix with whatever is there already (mostly nitrogen) - there is little or no pressure on it to condense to liquid or deposit as solid.
Oxygen, at temperatures (and pressures) on the earth, tends to prefer to be a gas.
You need oxygen to live because it functions in cellular respiration, which supplies you with energy. Oxygen is used up and carbon dioxide is produced. When you inhale, you are taking in oxygen to supply your body with it. When you exhale, you are releasing the carbon dioxide because your body doesn't need it. You don't release the same amount of oxygen that you breathed in because your body needs it.
Each time you breathe in your body goes through cellular respiration, which takes glucose (C6H12O6) and oxygen (O2) and turns it into water (H2O) Carbon Dioxide (CO2) and Energy (ATP), the Carbon Dioxide is breathed out in place of the used up oxygen. When you breathe in then all that oxygen is translated into carbon dioxide, as previously stated, which is breathed out.
The answer is if there was more oxygen then it would lead to a blast every time there was a spark
Sea water holds much less oxygen than air and even less as temperature increases.
Air: 210 mL oxygen per litre;
Water (0ºC): 8.0 mL per litre; water (20ºC): 5.4 mL per litre
Simple. The air around us has a lot more oxygen than water does. A fish can't breathe above water because it's taking in TOO much oxygen.
Oxygen is absorbed from inhaled air and used by the body, so there is less oxygen to be exhaled.
Air is a mixture of gases; the solubility of oxygen in water is limited.
Exhaled air contains 16% oxygen and 21% when inhaled.
Inhaled air contains more oxygen than carbon dioxide and other gases. Exhaled air contains mostly carbon dioxide as the inhaled oxygen was used up to create energy. Waste carbon dioxide (and other unwanted gases) is then let out of the body and the cycle continues. :)Gas exchangeGas% in inhaled air% in exhaled airOxygen2116Carbon dioxide0.044Nitrogen7979

You have about 20% oxygen in inhaled air and negligible carbon bi oxide. You have about 4% carbon bi oxide in the exhaled air. That means 4% of the oxygen is absorbed from the blood. That makes it 4%/20%= 20% of the oxygen from the inhaled air is absorbed in your blood.
Exhaled air - is the carbon dioxide that we breath out as a product of cellular respiration. Inhaled air is the oxygen we take in that is required for the process of cellular respiration. Along with the oxygen we take in are other elements such as Nitrogen, which we don't use and it doesn't harm us. It's just a by product of breathing.
Oxygen is the gas that demonstrates the largest difference in percent between air that is inhaled, and air that is exhaled. The symbol for oxygen is O.
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
Inhaled air is richer in oxygen than exhaled air.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
Inhaled air contains more oxygen than exhaled air because the cells have not yet used that oxyginated air.
Exhaled air contains 16% oxygen and 21% when inhaled.
Oxygen is inhaled and Carbon Dioxide is exhaled.
The hawk is bird not oxygen and the hawk inhaled oxygen and exhaled carbon dioxide.
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.
Exhaled air contains CO2 (Carbon Dioxide) and Inhaled air contains O2(Oxygen).
The chemical name of exhaled breath is carbon dioxide or CO2. The chemical name of inhaled breath is oxygen, or O2.
Exhaled air will contain all of the gases in regular air, except that it will have higher percentages of carbon dioxide and lower percentages of oxygen. (It still will have oxygen, or CPR wouldn't work.) It will also have water vapor from our lungs. The main gas in inhaled and exhaled air is nitrogen. This is followed by oxygen, then carbon dioxide, then other gases. Yes, there is still more oxygen exhaled than carbon dioxide, but at a smaller percentage than was inhaled. Chances are that your teacher is looking for the gas, carbon dioxide, as your answer, since that is the product of cellular respiration that is disposed of in exhaled air, but it isn't the main component of exhaled air.
