Liquid Nitrogen

Liquid nitrogen finds wide application in the fields of industry, medicine, agriculture, etc.  Liquid nitrogen has a boiling point of -193 degrees.  It is stored in vacuum flasks. 

In industries, it is used for shrink fitting, in superconducting systems, and in machining.  It also finds application in medicine, where it is used in removing warts and in cryogenic surgery. 

Liquid Nitrogen is commercially produced by the cryogenic distillation of liquid air.  Pure Nitrogen can also be liquified to produce liquid nitrogen.

Liquid Nitrogen should be handled with care as it may cause cold burns if it comes in contact with skin.
