Liquid nitrogen (LN 2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air.
Jul 18, 2022 · Liquid nitrogen is the liquefied form of the element nitrogen that's produced commercially by the fractional distillation of liquid air. Like nitrogen gas, it consists of two nitrogen atoms sharing covalent bonds (N 2 ). Sometimes liquid nitrogen is denoted as LN 2, LN, or LIN.
Oct 9, 2012 · Liquid nitrogen, which has a boiling point of -196C, is used for a variety of things, such as a coolant for computers, in medicine to remove unwanted skin, warts and pre-cancerous cells, and in...
Aug 16, 2020 · The temperature of liquid nitrogen is −195.79 °C (77 K; −320 °F). This is the boiling point of nitrogen. However, nitrogen can exist as a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Below this temperature, nitrogen forms a solid, while above its boiling point, nitrogen exists as a gas.
Liquid nitrogen is the current golden standard for cell and gamete preservation. • Liquid nitrogen storage is effective, but costly, and presents some practical and safety concerns. • Lyophilization has been successfully applied to mammalian spermatozoa. • Dry storage is a promising approach for long-term preservation of cells and gametes.
Large volumes of nitrogen gas are evolved from small volumes of liquid nitrogen (1 litre of liquid giving 0.7 m3 of vapour) and this can easily replace normal air in poorly ventilated areas leading to the danger of asphyxiation.
What is liquid nitrogen? Liquid nitrogen is formed when nitrogen is cooled to temperatures far below zero. The density of liquid nitrogen is 806.59 kg/m³ at atmospheric pressure and an energy capacity of 199.32 kJ/kg. In its liquid form, it manifests itself very similar to water.
May 25, 2024 · Liquid nitrogen, denoted as LN 2, is nitrogen in a liquid state at an extremely low temperature. It is a colorless clear liquid with a density of 0.807 g/ml at its boiling point and a dielectric constant of 1.43.

The liquid nitrogen boils around the food at a temperature of −196 °C (−321 °F) and extracts a large amount of heat. Read More.
Aug 14, 2019 · Liquid nitrogen is very cold! At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below 63 K, it freezes into solid nitrogen. Because liquid nitrogen in a usual setting is boiling, its usual temperature is 77 K.
