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

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

Liquid hydrocarbon fuels are the most commonly used forms of energy storage for use in transportation, but because the byproducts of the reaction that utilizes these liquid fuels ' energy ( combustion ) produce greenhouse gases other energy carriers like hydrogen can be used to avoid production of greenhouse gases.

Liquid propellants generally have densities similar to water ( with the notable exceptions of liquid hydrogen and liquid methane ), and these types are able to use lightweight, low pressure tanks and typically run high-performance turbopumps to force the propellant into the combustion chamber.

Liquid metallic hydrogen is thought to be present in large amounts in the gravitationally compressed interiors of Jupiter, Saturn, and some of the newly discovered extrasolar planets.

Liquid hydrogen engines were first successfully developed in America, the RL-10 engine first flew in 1962.

* Liquid oxygen and liquid hydrogen

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

* Liquid hydrogen

Liquid sterilants and high disinfectants typically include oxidizing agents such as hydrogen peroxide and peracetic acid and aldehydes such as glutaraldehyde and more recently o-phthalaldehyde.

* Liquid propellants can leak, especially hydrogen, possibly leading to the formation of an explosive mixture.

Liquid hydrogen must be kept colder than about 20 ° C above absolute zero ( 20 K or − 252 ° C or − 423 ° F ) so good insulation is very important.

* Liquid hydrogen ( LH < sub > 2 </ sub >) and liquid oxygen ( LOX ) for fuel cell operation and water production, with LOX also being used to provide breathing oxygen for the crew.

* Liquid hydrogen trailer

Liquid hydrogen storage tanks must also be well insulated to minimize boil off.

Liquid methane has 3. 2 times the energy density of liquid hydrogen and is easier to store.

Liquid hydrogen cyanide can be flushed with water.

Liquid hydrogen at-250 to-265 ° C can also be used as a coolant.

Liquid hydrogen is also used both as a fuel and as a coolant to cool nozzles and combustion chambers of rocket engines.

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 oxygen and kerosene or RP-1

* Liquid oxygen and ethanol

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 — abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries — is one of the physical forms of elemental oxygen.

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 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 ink electrostatic printers were mostly available in 36 inches to 54 inches width and also 6 color printing.

Liquid crystals were first developed in 1888.

The origins and the complex history of liquid crystal displays from the perspective of an insider during the early days were described by Joseph A. Castellano in Liquid Gold: The Story of Liquid Crystal Displays and the Creation of an Industry.

Liquid shapes became the trademark of Dalí, particularly in his The Persistence of Memory, which features the image of watches that sag as if they were melting.

A steady stream of Johnny Wadd films followed which included Tell Them Johnny Wadd is Here ( 1976 ), Liquid Lips ( 1976 ), The Jade Pussycat ( 1977 ), The China Cat ( 1978 ), and Blond Fire ( 1978 ), all of which were huge box office successes.

A third album, with the absence of John Petrucci, along with a fourth album, with the absence of Jordan Rudess ( mostly ), were released in 2007 & 2009 respectively, both under the name " Liquid Trio Experiment ".

On March 29, 2008, six Liquid Tension Experiment tour dates in June 2008 were announced to celebrate the bands 10 year anniversary as well to create a " whole new musical experiment ".

A few songs from Liquid Tension Experiment 2 were spawned from these jam sessions, including " 914 ", " Chewbacca ", and " Liquid Dreams ".

Recently K-Y Liquid, a warming lubricant, K-Y Warming, K-Y Intense ( for women ), and a dual-application liquid lubricant, K-Y Yours and Mine were introduced.

In Version 1. 1, more weapons were added, such as Napalm, Smoke Tracers, and Liquid Dirt as well as Joystick support and two new death animations among other things.

In the United States notable acid jazz groups have included Groove Collective, Brooklyn Funk Essentials and Grammy nominated Liquid Soul ; although during the 1990s the major contributions from the US to jazz fusion were predominantly in jazz-house ( from labels such as 8 Ball Records ) and jazz-rap, particularly by artists such as A Tribe Called Quest, Black Sheep, De La Soul, the Jungle Brothers, and Digable Planets.

There were a number of studies linking fatalities to the trichloroethane contained in correction fluids, including Liquid Paper.

Among the classic disco that was a staple in Chicago clubs at the time, typical tracks one could hear him play were Visage-" Frequency 7 ", Klein & MBO-" Dirty Talk ", ESG-" Moody ", Patrick Adams-" Big Phreek ", Liquid Liquid-" Optimo ", First Choice-" Let No Man Put Asunder ", a lot of Philly Soul Classics and even pop hits like Eurythmics-" Sweet Dreams " and Talk Talk-" It's My Life ".

In the early 1990s, his Dogboy stories were adapted by MTV as a live-action serial for Liquid Television.

By the end of the 1990s, Liquid crystal display ( LCD ) panels were increasingly favored among aircraft manufacturers because of their efficiency, reliability and legibility.

SPACEHAB module experiments that were activated included the Organic Separations payload, which is designed to investigate cell separation techniques for possible pharmaceutical and biotechnology processing, and the Equipment for Controlled Liquid Phase Sintering Experiment package, a furnace designed to explore the possibilities of creating stronger, lighter and more durable metals for use in bearings, cutting tools and electronics.

Also transferred to station were Mir Glovebox Stowage ( MGBX ) equipment to replenish glovebox already on station ; Queen ’ s University Experiment in Liquid Diffusion ( QUELD ) flown in orbiter middeck locker ; and High Temperature Liquid Phase Sintering ( LPS ) experiment.

These facilities were the Large Isothermal Furnace, the EXpedite the PRocessing of Experiments to the Space Station ( EXPRESS ) Rack, the Electromagnetic Containerless Processing Facility ( TEMPUS ) and the Coarsening in Solid – Liquid Mixtures ( CSLM ) facility, the Droplet Combustion Experiment ( DCE ) and the Combustion Module-1 Facility.

The exceptions are the final track, " Liquid " ( Demo ), which is a demo tape of their hit song " Liquid ", and the songs " F-F-F-Falling " and " Chill " which were the first new songs released after Aki replaced Janne.
