Liquid nitrogen (LN2) 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.
16 sie 2020 · The temperature of liquid nitrogen is −195.79 °C (77 K; −320 °F). Liquid nitrogen has many uses, but poses risks of frostbite, explosion, and suffocation if handled incorrectly. Liquid nitrogen is very cold! At room temperature and pressure, liquid nitrogen boils into nitrogen gas.
17 kwi 2017 · 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.
The boiling point of liquid nitrogen at normal atmospheric pressure is -196°C. Below this temperature, the substance transforms from gaseous to liquid. When the temperature rises above this point, the liquid form is lost, and nitrogen will return to its gaseous state.
25 lis 2010 · Liquid nitrogen is used to freeze foods, to preserve whole blood and other biologicals, and as a coolant. Nitrogen is nontoxic and noncombustible, but it may cause asphyxiation by displacement of air. Liquid nitrogen is very cold and and contact may cause frostbite.
2 dni temu · It is a cryogenic liquid with an extremely low boiling point: -196°C (-321°F). As such, liquid nitrogen is a clear, colorless liquid derived from nitrogen gas: it is therefore a cooling and preservation resource that is used across many industries, from medicine to food preservation and even industrial applications.
25 maj 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.
