Liquid nitrogen has many usages:

  • To freeze food instantaneously (flash freezing) so it can be preserved the way it looks and not let it sit in a freezer and let it change its physical structure over time.

    Similarly, for long term storage of viable cells like the sperm of animals such as bulls, race stallions, pedigree dogs, or humans in a sperm bank.

  • In the kitchen for molecular gastronomy or for the preparation of ice cream.
  • With superconductors that work better at extremely low temperatures.
  • In agriculture it is degassed and directly injected into the ground when a pure nitrogen fertilizer is required.
  • In chemical industry to make ammonia, nitric acid and other compounds.
  • In cryogenics.

Liquid nitrogen is used in cryobiology and cryotherapy, especially in dermatology. It is also used to freeze warts, pre-cancerous spots, and any other skin surface issues such as sun and age spots. The liquid nitrogen freezes the area, it turns dark (because the cells die) and falls off leaving new skin.

Can nitrogen used as a fuel in cars?

Yes , it can be. A living example is a Liquid Nitrogen Vehicle.A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary engine. Vehicles propelled by liquid nitrogen have been demonstrated, but are not used commercially.

Is liquid nitrogen used in refrigerators for cooling?

No. Refrigerators use a substance called Freon that can readily change from liquid to gas to liquid, moving heat from inside the fridge to the outside. Liquid nitrogen is FAR too cold, and requires too much energy to make the change from gas to liquid.Yes, liquid nitrogen is used in refrigerators. Nitrogen is a diatomic gas. The two nitrogen atoms are bond with a triple bond.
