Nitrogen Cycle

When the Earth was formed, nitrogen gas was the main ingredient in its atmosphere. Today, the Earth's atmosphere is about 78% nitrogen, about 21% oxygen, and about 1% other gases. This is an ideal balance because too much oxygen can actually be toxic to cells. In addition, oxygen is flammable.

Nitrogen | Afrox South Africa

Nitrogen is a colourless, odourless, non-toxic, almost totally inert gas comprising approximately 79% by volume of air. It is nonflammable and will not support combustion. Nitrogen is supplied in cylinders as a high-pressure gas, or in insulated containers as a liquid. Afrox MSDS no. 994-306. USES AND FEATURES OF NITROGEN

Nitrogen

Nitrogen is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The nitrogen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the nitrogen boiling point with changes in pressure.

Nitrogen (N2): Its Discovery, Danger and Uses

Nitrogen is the primary gas in the atmosphere. It makes up 78.084 percent by volume in dry air, and that makes it the most common gas in the atmosphere. Its atomic symbol is N and its atomic number is 7. The Discovery of Nitrogen Daniel Rutherford discovered nitrogen in 1772. He was a Scottish chemist and a physician with a passion …

Nitrogen in Transformers

Nitrogen, being an inert gas, reduces the risk of a fire hazard. It also protects the transformer oil and the transformer insulation from reacting with oxygen in the air and deteriorating. In transformers containing nitrogen, …

Types of Crushers: What You Need to Know

Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.

Nitrogen

Description [] Nitrogen can be mixed with Oxygen to stabilize its flammability and avoid Oxygen toxicity, and is a resource in its own right, useful for creating, a breathable atmosphere (at roughly 3:1 Nitrogen and Oxygen). The most efficient source of Nitrogen is from Ice (Nitrice) deposites found around the Solar System. You can …
