Nitrogen

 

Nitrogen is a non-reactive gas. It has no color, odor or taste. It comprises around 78% of the Earth’s atmosphere.

Nitrogen Uses

The most common types are nitrous oxide and supercoolant liquid nitrogen. This element is present in virtually all pharmacological drugs. In the form of nitrous oxide it is used as an anesthetic. Cryopreservation also uses the gas to conserve egg, blood, sperm and other biological specimens. The CPUs in computers use the gas to keep them from heating up. X-ray detectors also rely on this element.

 

Liquid Nitrogen

The element assumes this form at -195.5 degree and below. Its uses include refrigerants and cryotherapy. In the latter it is used to take out actinic keratosis, warts and treat other skin disorders.
