Liquid nitrogen refers to the element nitrogen in a liquefied state. This is a clear, colorless liquid which is produced via liquid air's fractional distillation. Liquid nitrogen has a temperature of -196°C / -321°F. It is classified as a cryogenic fluid which causes rapid freezing when it comes ...
Dec 28, 2018· 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.
LIQUID NITROGEN is very unreactive. Nonflammable, noncombustible and nontoxic. Vapors can fill closed spaces and asphyxiate. Contact with water may result in vigorous or violent boiling and extremely rapid vaporization. If the water is hot, there is the possibility that a liquid …
The gas maintained in a liquid state at a temperature of -321°F (-196°C) tries to escape and evaporate. It must be carefully carried in containers provided for this purpose, such as Dewar flasks, double-wall insulated vessels designed for liquefied gases. Keeping liquid nitrogen in an airtight container would turn it into a real pressure bomb ...
Liquid nitrogen Manufacture Nitrogen is produced at air separation plants by liquefaction of atmospheric air and separation of the nitrogen by continuous cryogenic distillation. The nitrogen is then recovered as a cryogenic liquid. Uses Nitrogen is the largest volume inorganic chemical sold in the world, supporting
Image by Pim Stouten/Flickr What Is Liquid Nitrogen & How Is It Produced? I'll let the professionals handle this one. Says Molecular Gastronomy Network, "The air we breathe is composed of approximately 78% nitrogen in its gaseous state, against 21% oxygen and 1% various other gases.To produce liquid nitrogen, the air is first liquefied and the nitrogen is then separated by distillation.

Liquid nitrogen expands 695 times in volume when it vaporizes and has no warning properties such as odor or color. Hence, if sufficient liquid nitrogen is vaporized so as to reduce the oxygen percentage to below 19.5%, there is a risk of oxygen deficiency which may cause unconsciousness. Death may result if oxygen deficiency is extreme.
