Liquid nitrogen is the most commonly used element in cryogenics and is legally purchasable around the world.

Liquid nitrogen, a fluid resembling water in appearance, but with 80. 8 % of the density ( the density of liquid nitrogen at its boiling point is 0. 808 g / mL ), is a common cryogen.

** Liquid nitrogen

Liquid nitrogen boils at 77 K, facilitating many experiments and applications that are less practical at lower temperatures.

Liquid nitrogen boils at 77 K, facilitating many experiments and applications that are less practical at lower temperatures.

Alternatively, heat may be supplied at ambient temperature and the heat sink maintained at a lower temperature by such means as cryogenic fluid ( see Liquid nitrogen economy ) or iced water.

* Liquid nitrogen cryosurgery is safe for pregnancy.

Liquid nitrogen is circulated through the end of this device.

Liquid nitrogen, supplied in pressurized steel bottles, is sometimes used in similar fashion.

Liquid nitrogen

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature.

Liquid nitrogen is a colorless clear liquid with density of 0. 807 g / mL at its boiling point and a dielectric constant of 1. 4.

Liquid nitrogen is often referred to by the abbreviation, LN < sub > 2 </ sub > or " LIN " or " LN " and has the UN number 1977.

Liquid nitrogen can easily be converted to a solid by placing it in a vacuum chamber pumped by a rotary vacuum pump.

Liquid nitrogen freezes at.

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

Liquid nitrogen is produced commercially from the cryogenic distillation of liquified air.

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 nitrogen vehicle

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.

In the construction industry a specialised proprietary adhesive known as Liquid Nails ( or liquid nails as the generic ), is used.

Liquid chromatography ( LC ) is a separation technique in which the mobile phase is a liquid.

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

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.

* Timothy J. Sluckin History of Liquid Crystals, a presentation and extracts from the book Crystals that Flow: Classic papers from the history of liquid crystals.

Liquid crystals ( LCs ) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal.

Liquid crystals find wide use in liquid crystal displays, which rely on the optical properties of certain liquid crystalline substances in the presence or absence of an electric field.

Liquid crystal lasers use a liquid crystal in the lasing medium as a distributed feedback mechanism instead of external mirrors.

Liquid column gauges consist of a vertical column of liquid in a tube that has ends which are exposed to different pressures.

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 flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses.

Liquid flows into the pumps as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses.

Liquid and slurry pumps can lose prime and this will require the pump to be primed by adding liquid to the pump and inlet pipes to get the pump started.

Liquid pressure also depends on the density of the liquid.

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.

A similar product, called the Liquid Flavor Injector, allowed for the injecting of liquid ingredients into meat, e. g., lime juice into chicken.

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 helium also has this property, but, in the case of He-II, the flow of the liquid in the layer is not restricted by its viscosity but by a critical velocity which is about 20 cm / s.
