Liquid nitrogen: History & Applications

Liquid nitrogen (LN2) is nitrogen in a liquid state at low temperature. It has a boiling point of about −196 °C (−321 °F; 77 K). Liquid nitrogen is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about half that of acetone (i.e. roughly one-sixth that of water at room temperature).…
