Compressed air? What state?

Question

Am puzzled by the relative 'state' of air that is held in a compressed cylinder (for breathing apparatus) If you can get 30 mins of breathing out of just 6 litres, it must be compressed heavily, but is it still in a gaseous state, or has it turned into a liquid?

Answer 1

pressurized gases have a threshhold at which it resists turning into liquid and developing a temperature solid mass also has a thresh hold at which it resist a transfer to liquid although the result is heat liquidification of solid mass called plasma this is called fussion most canisters use semi liquid state or threshhold packing

Answer 2

The oxygen is still in gaseous form, however the water content that is in the same cylinder can become liquid under compression.

Answer 3

It's not compressed enough to turn into a liquid, so its just a compressed gas.
Its also a mixture of gases, so compressing it too much would separate the various gases from each other which would be bad. All gases will form a liquid with enough pressure regardless of the temperature.

Answer 4

still a gas dude!

I charge my PCP rifle up to 230Bar which is the same pressure as most dive bottles.

now when i'm taking a 30yard shot at a bunnies head, the last thing I want is liquefied air sloshing round in my cylinder - i might miss and the dog will go hungry!!

Answer 5

Liquid.

Answer 6

it is in a gaseous state, oxygen only turn to a liquid state under extreme cold temperatures.

Answer 7

Still a gas, though highly compressed.

b'cause , a liguid air LPG is stated clearly as Liquified petroleum gas
or even liquid Nitrogen.... etc

Answer 8

It is still a gas, although the temperature of the boiling point does go up

Answer 9

liquid state

Answer 10

still air even if its compressed
