What is liquid nitrogen??(⌐■-■)
Answers
Liquid nitrogen—LN₂—is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −195.8 °C. It is produced industrially by fractional distillation of liquid air. It is a colorless, low viscosity liquid that is widely used as a coolant.
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 cryogenics, where scientists study the effect of very cold temperatures on materials.
According to the Food and Drug Administration, liquid nitrogen is non-toxic but can cause severe damage to skin and internal organs if mishandled or ingested because of the extremely low temperatures it maintains.
