Our atmosphere, to which we are uniquely adapted, is about 78% nitrogen, 21% oxygen, and 1% everything else. It has changed very gradually over the millions of years, but that's where we are right now. Let's not mess with it.
Nitrogen(78%);Oxygen(21%);Noble gases such as Helium, Neon, Argon etc.(0.94%); Carbon dioxide(0.03%);Others(0.03%).
atmosphere gases are made of air
The active gas in the air is HYDROGEN
water vapor is different from other gases that make up air because it condenses out of air that has cooled
Dirty air is gases and smoke that prevents smelly and unfresh air.Dirty air also comes from car engens and truck gases,it can come from factorys aswell.
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
Well I think its true
What gases cause air pollution
Yes. The gases ARE the air.
Gases displace oxygen, and heavy gasses will sit under oxygen containing air, hence if you are in a confined space it is necessary to know about the potential lack of air supply to breathe, aswell as the potential of combustion and the like.
a supply of air
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.

the cam is the part of your engine that opens your valves to allow in fuel air mix and let out exhaust gases
Without different gases there will be no air, if there is air, how can oxygen travel?
Yes. Neon is a part of noble gases (or inert gases)
