Nitrogen makes up 78% of air, so we obviously breathe it in and because our body doesnt 'NEED' Nitrogen, so however much you inhale, you can exhale the same amount as none of the Nitrogen is used up. hope it helped ;p x
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
The air is made up, mostly, of oxygen and nitrogen.. Air is 78 % nitrogen, 21 % oxygen, about 1 % argon, and a whole raft of other gases present in even smaller amounts..
The nitrogen is not absorbed in your body via lungs. So the amount of nitrogen in inhaled and exhaled air has to be same. Nitrogen protects your body from the harmful effects of 100 % oxygen.
The temperature of the liquid nitrogen is so low that it freezes water molecules from the air which forms as ice at the opening.
There is about 78.09% of nitrogen in the air.
Air is 78% Nitrogen
Air contains about 78% nitrogen by volume.
Nitrogen dioxide in air = 0.02 ppm
The atmosphere is 78.08% Nitrogen78%70%
Air is 78% nitrogen, and most tyres are inflated with air, so mixing pure nitrogen with air would not be a problem.
78%
78% 0of the air we breathe is nitrogen, same as the amount in the air.
Air is about 78% nitrogen pretty much everywhere on Earth.
The air all around us contains 78.09% nitrogen, so the air in your house will contain nitrogen.
The air is already 78% nitrogen, so nitrogen doesn't pollute air. That being said, the nitrogen in air reacts under high heat and/or pressure such as an engine or combustion process to make nitrogen oxides which are toxic or can combine with water to make acid rain, or combine with reactive hydrocarbons in the presence of ultraviolet light to make photochemical smog.
The Earth's atmosphere contains 78% nitrogen.
