	Liquid Oxygen
		Oxygen is the second largest component of the atmosphere, comprising 20.8% by volume.
		Oxygen is often stored as a liquid, although it is used primarily as a gas.
		Oxygen may be withdrawn as a gas by passing liquid through an internal vaporizer or as a liquid under its own vapor pressure.

	Liquid Oxygen
		Liquid oxygen also reffered to as LOX, is a versatile and efficient means of supplying oxygen to the home patient.
		The container consists of a lower portion where the oxygen is in a liquid state and a smaller upper portion where the liquid has evaporated creating a gas.
		Liquid oxygen passes through a warming coil, is converted to a gas, and is made available for patient delivery.

	math lessons - Liquid oxygen
		Liquid oxygen has a density of 1140 kg/m³ and is moderately cryogenic (freezing point: −219 °C, boiling point: −183 °C).
		Liquid oxygen is a powerful oxidising agent: organic materials will burn rapidly and energetically in liquid oxygen, hence LOx is a common liquid oxidizer propellant for spacecraft rocket applications usually in combination with liquid hydrogen or kerosene.
		Liquid nitrogen has a significantly lower boiling point (77 K) than oxygen (90 K), and vessels containing liquid nitrogen can condense oxygen from air: when most of the nitrogen has evaporated from such a vessel there is a risk that liquid oxygen remaining can react violently with organic material.

	Oxygen - Wikipedia, the free encyclopedia
		People who climb mountains or fly in depressurized aeroplanes sometimes have supplemental oxygen supplies; the reason is that increasing the proportion of oxygen in the breathing gas at low pressure acts to increase the inspired oxygen partial pressure nearer to that found at sea-level.
		A notable application of oxygen as a very low-pressure breathing gas, is in modern spacesuits, where use of nearly pure oxygen at a total pressure of about 1/3rd normal, results in normal blood partial pressures of oxygen.
		In the case of spacesuits, oxygen partial pressure in the breathing gas is typically about 0.30 bar (1.4 times normal), and oxygen partial pressure in the astronaut's blood (due to downward adjustments due to water vapor and CO in the alveoli) is close to sea-level normal of 0.14 bar.
