How can we use liquid nitrogen? What are the purposes of using liquid nitrogen?​

Answer 1

Liquid nitrogen is a very cold and versatile chemical which has numerous uses in applications such as cooling, cryogenics, material preservation, and other industrial processes. Its incredibly low temperature (-196 degrees Celsius/-320 degrees Fahrenheit) makes it an excellent coolant and refrigerant for various materials. These uses can range from food preservation to semiconductor production. It is also used as a cryogenic in medical procedures such as cryosurgery and as a propellant in rocket fuel.

Answer 2

Liquid nitrogen can be used to freeze biological tissue. Liquid nitrogen is -210°C which will stop all biological decomposition in the tissue and preserve it.
