Liquid oxygen is used as an oxidizer of hydrogen, but oxygen is not, strictly speaking, a fuel.

Liquid oxygen is attracted to a magnet to a sufficient extent that, in laboratory demonstrations, a bridge of liquid oxygen may be supported against its own weight between the poles of a powerful magnet.

Liquid hydrogen and oxygen were also used in the Space Shuttle to run the fuel cells that power the electrical systems.

Liquid nitrogen may be produced for direct sale, or as a byproduct of manufacture of liquid oxygen used for industrial processes such as steelmaking.

Liquid oxygen has a pale blue color and is strongly paramagnetic and can be suspended between the poles of a powerful horseshoe magnet.

Liquid oxygen has a density of 1. 141 g / cm < sup > 3 </ sup > ( 1. 141 kg / L ) and is cryogenic with a freezing point of 50. 5 K (− 368. 77 ° F ; − 222. 65 ° C ) and a boiling point of 90. 19 K (− 297. 33 ° F, − 182. 96 ° C ) at 101. 325 kPa ( 760 mmHg ).

Liquid oxygen has an expansion ratio of 1: 861 at 20 ° C ( 68 ° F ); and because of this, it is used in some commercial and military aircraft as a source of breathing oxygen.

Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid oxygen.

Liquid nitrogen has a lower boiling point at − 196 ° C ( 77 K ) than oxygen's − 183 ° C ( 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.

Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.

Liquid oxygen is a common liquid oxidizer propellant for spacecraft rocket applications, usually in combination with liquid hydrogen or kerosene.

Liquid oxygen is useful in this role because it creates a high specific impulse.

Liquid oxygen was also used in some early ICBMs, although more modern ICBMs do not use liquid oxygen because its cryogenic properties and need for regular replenishment to replace boiloff make it harder to maintain and launch quickly.

* Liquid to solid cycle ( Frost heaving — water changing from ice to liquid and back again can lift rock up to 60 cm.

Liquid hydrogen has extremely low density ( 14 times lower than water ) and requires extensive insulation — whilst gaseous hydrogen requires heavy tankage.

* Liquid based cytology — The Pap smear sample is put in a bottle of preservative for transport to the laboratory, where it is then smeared on the slide.

* Liquid funk — Netsky, High Contrast, Nu: Tone & London Elektricity

* Comcast Center in Philadelphia, PA — Contains the largest Tuned Liquid Column Damper ( TLCD ) in the world at 1, 300 tons.

Liquid helium is used as a coolant for most superconductive windings, even those with critical temperatures far above its boiling point of 4. 2 K. This is because the lower the temperature, the better superconductive windings work — the higher the currents and magnetic fields they can stand without returning to their nonsuperconductive state.

# Liquid storage — Liquid oxygen is stored in chilled tanks until required, and then allowed to boil ( at a temperature of 90. 188 K (− 182. 96 ° C )) to release oxygen as a gas.

The Green Beret ( 1991 ) ( which was featured in an episode of " Liquid Television "; MTV misspelled his name " Hillenberg " in the credits ) and Wormholes ( 1992 ) became popular shorts in several film festivals — and received various awards.

Liquid silicone was used for lip augmentation, starting in the early 1960s but was abandoned thirty years later due to general — and later, unfounded — fears about the effects of silicone on general health.

* 1944 – Liquid natural gas leaks from storage tanks in Cleveland, then explodes ; the explosion and resulting fire level 30 blocks and kill 130.

Liquid argon is typically cheaper and can be stored in a greater quantity as opposed to the gas form, which is more expensive and takes up more tank space.

* Liquid petroleum gas 47 km

Other utility companies serving El Dorado and surrounding areas include Centerpoint Energy ( natural gas ), Southern Lp-Gas Inc ( Liquid Gas ), Bcs Inc ( Commercial and Residential Bottled Gas, Metered Gas Service ), Suddenlink Television ( Cable TV, Internet and Phone ), Verizon Wireless, AT & T ( residential and wireless phone services ), among others.

On August 21, 1967 a French tanker lorry containing 45. 000 litres of Liquid gas suffered from failing brakes while driving downhill.

* Liquid ( as a gas is also a ' fluid ') does not absorb any of the supplied energy.

Liquid nitrogen is a compact and readily transported source of nitrogen gas without pressurization.

In the BWR, soluble neutron absorbers are found within the Standby Liquid Control System, which uses redundant battery-operated injection pumps, or, in the latest models, high pressure nitrogen gas to inject the neutron absorber solution into the reactor vessel against any pressure within.

Liquid propane, which expands into a gas, has also been used.

* Liquid propellants often need ullage motors in zero-gravity or during staging to avoid sucking gas into engines at start up.

The final item donned before putting on the pressure suit is the " Liquid Cooling and Ventilation Garment " ( LCVG ), which incorporates clear plastic tubing through which chilled liquid water flows for body temperature control, as well as ventilation tubes for waste gas removal.

If the cylinder's contents are liquid, but become a gas at ambient conditions, this is commonly referred to as a Boiling Liquid Expanding Vapour Explosion ( BLEVE ).

Liquid carburizing involves placing parts in a bath of a molten carbon-containing material, often a metal cyanide ; gas carburizing involves placing the parts in a furnace maintained with a methane-rich interior.

Liquid – gas transitions do have a higher heat of transformation than solid – liquid transitions.

Proteomics and metabolomics have no standardized procedures yet, but usually, proteome analysis is done by two-dimensional gel electrophoresis and Liquid chromatography-mass spectrometry, while metabolome analysis is conducted through gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry and liquid chromatography-nuclear magnetic resonance.

Liquid oxygen is provided to hospitals for conversion to gas for patients suffering from breathing problems, and liquid nitrogen is used in the medical field for cryosurgery, and by inseminators to freeze semen.
