Answer:

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.
