What is oxygen content of the body?
the air in his body
What would happen to the oxygen content of air?
if............?
What is the approximate percentage of oxygen in the atmosphere?
Earth's atmosphere is about 21% oxygen by volume (for dry air).
How does oxygen content change with altitude?
The density of air decreases with altitude, so the ratio of oxygen in the air stays the same, but the amount of gases in your lungs decrease.
Why does sulfur burn more rapidly in oxygen than in air?
Well, oxygen supports burning. Fire needs fuel, oxygen and a spark or another source of ignition. So the more oxygen there is, the faster your substance will burn! There is 21% oxygen in air, and when you have an atmosphere of oxygen, it can go to quite high concentrations. So sulphur will burn in an atmosphere which has a higher oxygen content.
What is the approximate oxygen content of air?
twenty per cent
What is the oxygen content of air at lower temperatures?
Air has 20% oxygen, no matter what the temperature.
What is the oxygen content of air?
The oxygen content of air is approximately 21%. Nitrogen is the largest component of air as it takes up 78% of the atmosphere.
What would happen to the oxygen content of air?
if............?
What is oxygen content of the body?
the air in his body
How can you choke on air?
If the nitrogen or carbon dioxide content in the air is too high, or if the oxygen content of the air is too low.
What would have to the oxygen content in the air if photosynthesis were stop?
The oxygen content in air would have decreased. This is because photosynthesis is a process which keeps the balance between oxygen and carbon dioxide by converting carbon dioxide to oxygen.
What is the approximate percentage of oxygen in the atmosphere?
Earth's atmosphere is about 21% oxygen by volume (for dry air).
What are the differences between the surrounding air and exhaled air?
The air you breathe out is little changed from the air you breathe in, except that the oxygen content is somewhat lower - your body extracts some (not all) of the oxygen. The exhaled air is the same except for slightly lowered oxygen content.
What is the average oxygen level in the air at 5000 ft?
The oxygen content of air at any altitude is always about 21%
When air conditioner in vehicle working by closing external air inlet then will the amount of oxygen reduce if how oxygen content is maintained?
The general answer is "no, the oxygen in the vehicle compartment is unaffected by the air conditioning unit". The vehicle is not air-tight so while there may be a small decrease in oxygen content, sufficient oxygen for normal occupant breathing will remain.
How does the oxygen and carbon dioxide content of exhaled air differ from inhaled air?
Exhaled air has more carbon dioxide and less oxygen than does inhaled air.
