In recreational diving, most divers use compressed air (as in the normal air we breather at the surface). Some divers are also trained to use special gas mixes called Nitrox which have a higher oxygen content and lower Nitrogen.
Professional (or commerical) divers tend to use more advance mixes such as Heliox or Trimix which combine Oxygen, Nitrogen and Helium.

Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Some advanced divers dive using gas mixtures including Helium.
The air inside SCUBA tanks is, usually, just regular air that has been compressed and "jammed" into a tank. Some diving applications utilize gas mixtures of oxygen, nitrogen (and sometimes hydrogen).
It is Gas didn't you take a class on this
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
????? gaseous exchange INSIDE the scuba cylinder? There is no exchange of gasses in the cylinder, that is done in the LUNGS! A scuba Cylinder (or Tank for the americans) is a basic unit that holds compressed Gas (either AIR -21% oxygen and 79% nitrogen) NITROX (anything from 22% to 40% oxygen) Heliox (18% oxygen 40% helium rest nitrogen) All that occurs is that the unit supplies the gas inside to a REGULATOR system fitted to the valve then to the Demand valve in the divers mouth. No gas EXCHANGE is done here at all, only pressure restrictions. Gas exchange happens once the Gas has entered the Lungs, there the Alveoli take the gas (mostly the oxygen) and pass it to the blood stream, and pass the Carbon Dioxide back into the lungs to breathe out.
Anything pressurised with gas - an auto tire for example, or a scuba diver's air tank.
The solvent of diver's gas tank is surely oxygen and the solute is the helium,, Daisy Ann from Saint Paul
