g. Liquid Nitrogen
Liquid nitrogen is the liquid form of nitrogen stored at a very low temperature state. It is used by heating the fluid in a heat exchanger, which then extracts the heat in the form of a pressurized gas that is used to work an engine. The benefit of using liquid nitrogen simply involves heating it, which then returns the nitrogen to the atmosphere from which it came.
