When you put a gas into a cylinder the particles move all over the place by a process called diffusion. Even though they have a different molecular weight, the heavier molecules do not settle at the bottom of the tank. You could take a sample of air from anywhere in the tank and it would be similar. This means it is homogeneous.

How can you fill a tank of compressed air without an air compresser?
You can use a scuba tank, but that is it.
Mixture of gases for scuba diving tanks compared to normal atmospheric air?
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
What is the name of a compressed air cylinder used in skin diving?
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
Is the oxygen and nitrogen in a scuba tank considered a heterogeneous?
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
What does psi mean in scuba diving?
the amount of air in the tank per square inch. (p.s.i.)Improve answerPounds per Square Inch - so the amount of pressure exerted on the tank by the air under pressure in the cylinder of the scuba diver. The more pressure, the more compressed the air so the greater the volume of air compressed within the cylinder.for more on scuba diving, including equipment see the related link:
What should scuba air smell like?
Compressed air used for SCUBA should smell like regular air. There may be a slight rubber smell from the regulator. When in doubt, it is safer to get your tank refilled than to dive on contaminated air.
Would a scuba divers tank filled with compressed air last longer than normal pressure air?
It definitely would. Also, a tank filled with non-compressed air would be nearly impossible to use because air wouldn't flow out of it without an enormous amount of effort. For these reasons, all tanks used by divers are filled with compressed air.
You want to convert a SCUBA tank for use as CNG tank?
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
Examples of air being compressed?
In a bicycle pump, air is compressed when the handle is pumped, increasing the pressure inside the tire. Air is compressed in a scuba diving tank when it is filled with high-pressure air from a compressor. In a refrigerator or air conditioning system, a compressor compresses the refrigerant gas to increase its pressure and temperature.
Why can scuba diving tanks hold lots of air?
Because the air is compressed so that the same amount of air fills much less space meaning more can be put into a SCUBA cylinder. Normally a tank will be pressurised up to around 3000psi/200bar of pressure.
What is in scuba tank?
A scuba tank holds compressed air or a mix of gases, typically oxygen and nitrogen, that divers breathe underwater. The tank allows divers to stay submerged for extended periods by providing them with a continuous air supply.
What do the numbers mean on a scuba tank?
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.
