Solid nitrogen is a number of solid forms of the element nitrogen, first observed in 1884. Solid nitrogen is mainly the subject of academic research, but low-temperature, low-pressure solid nitrogen is a substantial component of bodies in the outer Solar System and high-temperature, high-pressure solid nitrogen is a powerful explosive, with ...
Solid nitrogen has many crystalline modifications. It forms a significant dynamic surface coverage on Pluto [51] and outer moons of the Solar System such as Triton. [52] Even at the low temperatures of solid nitrogen it is fairly volatile and can sublime to form an atmosphere, or condense back
It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts. Nitrogen compounds also have an important role in organic chemistry, as nitrogen is part of proteins, amino acids and adenosine triphosphate.
Solid: A solid holds a definite shape and volume without the need of a container. The particles are held very close to each other. Amorphous solid: A solid in which there is no far-range order of the positions of the atoms. Crystalline solid: A solid in which atoms, molecules, or ions are packed in regular order.
Broadly speaking, the term "solid state" refers to using a solid material for both the separator that keeps anode and cathode from touching and the medium through which the electrons pass as the ...
The program is capped at 65,000 news visas each year, although an additional 20,000 can be issued for employees with a master's degree or higher, according to the U.S. Citizenship and Immigration ...
The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a vacuum pump. [2] Liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in an insulating layer of ...
An Azerbaijani airliner carrying 67 people crashed near the city of Aktau in Kazakhstan on Wednesday, killing at least 38 who were on board, according to a Kazakh official.
