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.

Why is oxygen in a scuba tank compressed?

It's compressed so they can fit fit more oxygen in it. In face it's compressed so much that it actually turns into a liquid.

Is air in a scuba tank a solution?

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).

What causes the pressure inside a scuba tank?

The compressed air pushing against the inside of the scuba tank causes pressure inside 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.

How can you fill a tank of compressed air without an air compresser?

You can use a scuba tank, but that is it.

How is compressed oxygen defined?

Compressed oxygen--oxygen that is stored as a gas in a tank.

What do the numbers mean on a scuba tank?

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 is the name of a compressed air cylinder used in skin diving?

Can you store cng in a scuba 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

Why do you need oxygen cylinders when you go scuba diving?

The simple answer is ... you don't. A majority of scuba dives use compressed air in the cylinders. Therefore you don't need "oxygen" cylinders. HOWEVER, if you are a diver that is diving on Nitrox, in which divers change the amount of oxygen vs nitrogen in their air, then your tank needs to be "oxygen clean" because you are putting oxygen in first, then nitrogen.

What type of oxygen is in a scuba tank?

Unless you've been specially trained to use any other form of air, it's the same as normal air, just compressed with impurities removed.

Is old gas in a scuba tank dangerous to breathe?

The nitrogen and oxygen we breathe on this planet is a billion years old and still is safe. So I doubt nitrogen and oxygen in a scuba tank would make any difference.

Is oxygen a compressed gas?

Oxygen can be compressed and using a diving situation either in a mix with other gases such as in normal air or special mixes i.e. Trimix, Nitrox etc. Or it could be compressed and used on its own. Compressed oxygen on its own is usually only used in rebreathers where the exhaled gas is reoxygenated. In short, oxygen can be compressed on its own or with other gases for use in SCUBA diving

Is compressed air in a scuba diver's tank a pure substance?

No it is not by any means. it is atmospheric air compressed with the high amounts of carbons and other gases lowered or removed.

Why do scuba divers breathe compressed air?

so that more air can be stored in the tank for longer stay underwater.

Why scuba diver wear oxygen tank?

so they can breath underwater

Is the oxygen and helium in a scuba tank an example of a homogeneous mixture?

yes, it is.

How much does scuba gear weigh?

Different scuba gear types weigh different amounts. The oxygen tank is the heavy part of the scuba diving gear.

Does pressure have any effect on the oxygen level in the scuba tank?

I'm not quite sure that I understand your question .... Are you asking: a) does it effect the percentage of oxygen in the air in the scuba tank? -No. If you're diving compressed air, it's always 21% Oxygen, 79% Nitrogen, just like air (ignoring the 1% other). If you're diving Nitrox (where divers play with the oxygen levels, it still stays the same as it was when they filled their tanks) b) does it effect how many breaths worth of air you're going to get out of the tank? - Yes. The deeper you go, the quicker you will deplete the tank.

What kind of gas is there in a oxygen tank?

Oxygen tanks have oxygen gas which is compressed and tightly sealed in the container.
