Liquid nitrogen is used as a refrigerant or as a source of gaseous nitrogen, i.e. it is used as a method of transporting gas.
Properties Liquid nitrogen is an odorless colorless liquid with a boiling point of 77.35 K at a pressure of 101.3 kPa and a specific volume of 1.239 dm3 / kg at a temperature of 77.35 K and a pressure of 101.3 kPa. Gaseous nitrogen is an inert gas without color and odor with a density of 1.25046 kg / m3 at 0 ° C and a pressure of 101.3 kPa. The specific volume of gaseous nitrogen is 860.4 dm3 / kg at a pressure of about 105 Pa and a temperature of 290 K.
Danger to humans. Liquid nitrogen in contact with the skin and mucous membranes causes frostbite and damage.
