Pressurized oxygen is O2 that is under more than the normal air pressure of 24 pounds per square inch.
Compressed oxygen--oxygen that is stored as a gas in a tank.
An external oxygen delivery system would consist of an oxygen source (such as a pressurized gas chamber), a pressure relieving system and a delivery system such as a breathing tube.
actually compressed oxygen does actually have weight.
The air is super compressed either in gas or liquid form in a pressurized tank. A regulator is attached and lets only a certain amount of psi through at a time. Without this regulator the bottle would take off like a rocket to the moon if it were to open somehow.
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.

Pressurized oxygen can be very dangerous and pose a hazard of explosion when exposed to heat sources, unlike other common compressed gasses such as nitrogen and carbon dioxide. The less pressurized the oxygen is, the smaller the risk of this happenning. Filling a tank to the gauge minimum instead of the maximum allowable mitigates risk to anyone who may be around it.

Mostly not enough oxygen in the air at the low pressure up there.

The percentage of Oxygen in the air is the same in airplane as it is outside the airplane. The only difference is the pressure levels. If the pressure drops too much then the total amount of Oxygen will be insufficient for you to breath and you will pass out. The airplane only carries oxygen for use in emergency and is dispensed in the oxygen masks of the crew and passengers. Maybe your Question is asking what the total volume of oxygen is available in a pressurized airplane. I don't know that.

fuels combust with greater efficiency in a compressed environment due to the higher content of oxygen molecules within the defined space, under pressure you will also get an explosion due to the sudden increase in pressure within the already high pressure environment
