The same reason every other gas in a scuba cylinder is compressed. If a cylinder is pressurized, then the gas in it is compressed by definition. If it is not pressurized, then there is obviously no gas in the cylinder to breath.

Nitrogen is added to Scuba tanks as part of the breathing gas mixture to dilute the higher oxygen content. This helps reduce the risk of oxygen toxicity at deeper depths while still providing enough oxygen for the diver. Oxygen toxicity can be dangerous for divers, so nitrogen is used to make the gas mixture safer for breathing.

∙ 6y agoI assume you mean proportion, not concentration - but it reflects the nature of the atmosphere, which is mainly nitrogen. At the other end of the scale, pure oxygen becomes toxic under pressure but I believe is used with great care as a decompression aid.

Nitrogen is 78% of air, so simply compressing air means that the partial pressure of nitrogen will be higher than the partial pressure of oxygen. This has importance in deep diving, as nitrogen also dissolves in the blood and can form dangerous bubbles if you decompress too rapidly.

∙ 8y agoAt the temperatures and pressure found on Earth, oxygen is a gas. As with all gasses, there is plenty of space between the molecules of oxygen gas, meaning there is room to compress it.

Scuba tanks have wh at noble gas in them?
Scuba tanks are typically filled with compressed air, which is a mixture of oxygen and nitrogen. However, some scuba tanks may also contain a noble gas such as helium as part of a special gas mix called trimix, which is used for deep dives to reduce the risk of nitrogen narcosis.
What is the air mixture in scuba?
The air mixture in scuba diving tanks is typically compressed air, which consists of about 21% oxygen and 79% nitrogen. This mixture allows divers to breathe at depth without experiencing adverse effects of high pressure.
How do scuba divers sink if they have tanks of compressed air on their backs?
Scuba divers use weights to sink during a dive because the air tanks on their backs make them buoyant. By adjusting the amount of weight, divers can achieve neutral buoyancy underwater. This allows them to control their depth and movement throughout the dive.
What are helpful uses of nitrogen?
It is used to purge moisture from optics. It is used in hydraulic accumlators and in recoil mechanisms of tanks and artillery.
Is the oxygen and helium in a scuba tank a pure substance?
Yes, the oxygen and helium in a scuba tank are pure substances because they consist of only one type of molecule and cannot be separated by physical means.
Scuba tanks have wh at noble gas in them?
Scuba tanks are typically filled with compressed air, which is a mixture of oxygen and nitrogen. However, some scuba tanks may also contain a noble gas such as helium as part of a special gas mix called trimix, which is used for deep dives to reduce the risk of nitrogen narcosis.
What are scuba tanks made of?
Most scuba tanks are filled with simple purified air. However, some are filled with oxygen enriched air called 'nitrox' or (less commonly) a blend of helium, oxygen and nitrogen called 'trimix' or (even less commonly) helitrox or heliox.
Why only oxygen is not used in tanks of scuba divers?
Naturally the air we breath has 70% of nitrogen and only 21% of oxygen, this is done is scuba diving as well. Just oxygen is not enough for living, while oxygen is essential one.
Are scuba tanks hydraulic or pneumatic?
SCUBA tanks are metal (usually steel or aluminum) that are filled with compressed air. This is loosely related to a pneumatic system.
What is the air mixture in scuba?
The air mixture in scuba diving tanks is typically compressed air, which consists of about 21% oxygen and 79% nitrogen. This mixture allows divers to breathe at depth without experiencing adverse effects of high pressure.
What is an example sentence for the word tanks?
Hide behind those water tanks. The scuba tanks are filled and ready to go.
Where can you get scuba tanks refilled other than at scuba shops?
You could buy your own portable diving compressor, my dive buddy has one, there not silly expensive . You must get fills from a compressor designed for diving (breathing) as the air is filtered and moisture removed.
Is there a certain temperature to keep tanks for scuba diving?
Under 25
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.
Fluid technologies that make use of air?
Fluid logic.
Do tanks that fill CO2 also fill nitrogen tanks?
No, they cannot.
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.
