Liquid Nitrogen At Room Temperature

Liquid nitrogen is used in several industries owing to its inertness and extremely low temperature levels.

Liquid nitrogen at room temperature. Nitrogen has a low melting and boiling point and is a gas at room temperature. Liquid nitrogen has a boiling point of 320 f 196 c. Liquid nitrogen facts. 320 f boiling point at sea level it is produced industrially by fractional distillation of liquid air it is a colorless low viscosity liquid that is widely used as a coolant.

Sometimes liquid nitrogen is denoted as ln 2 ln or lin. At atmospheric pressure the volume of 28 grams of nitrogen gas is 22 4 liters. Like nitrogen gas it consists of two nitrogen atoms sharing covalent bonds n 2. These are referred to as critical temperatures and pressures.

For every temperature there is a minimum pressure required to establish and maintain the liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below 130 f 90 c. Then the gas expands another 3 7 times as it warms to room temperature. Since 11 2 22 4 0 5 t p 0 5.

The next most common gas is oxygen at 21. The earth s atmosphere is made up of 78 nitrogen. Liquid nitrogen ln 2 is nitrogen in a liquid state at low temperature 195 79 c 77 k. Liquid nitrogen is the liquefied form of the element nitrogen that s produced commercially by the fractional distillation of liquid air.

Another hazard of liquid nitrogen is that the liquid expands to 174 6 times its original volume when it becomes a gas. Nitrogen density and specific weight online calculator figures and tables showing density and specific weight of nitrogen n 2 at temperatures ranging from 175 to 1325 c 280 to 2400 f at atmospheric and higher pressure imperial and si units. The volume of 28 grams of nitrogen liquid is 11 2 liters. A united nations number un or unid is a four digit code used to identify flammable and.

Liquid nitrogen is a cryogenic liquid. Because the liquid to gas expansion ratio of nitrogen is 1 694 at 20 c a tremendous amount of force can be generated if liquid nitrogen is rapidly vaporised in an enclosed space. The temperature difference between the product and the surrounding environment even in winter is substantial.
