Definition
Liquid nitrogen is a chemical that is super cold, about -200 degrees Celsius.

Liquid nitrogen: Nitrogen in a liquid state. Liquid nitrogen is supercool -- about 200 degrees Celsius (320 degrees Fahrenheit) below zero -- and is used for cryopreservation, cryosurgery, and cryomedicine.

Liquid nitrogen will instantly freeze anything it touches. It is used to kill cells that make up diseased or cancerous tissue. Tissue that has been frozen dries out and falls off.
