Liquid Nitrogen Facts Liquid Nitrogen Facts. 1  Liquid nitrogen is the liquefied form of the element nitrogen that is commercially produced by fractional distillation of liquid air. 2  Sometimes liquid nitrogen is denoted as LN 2, LN, or LIN. 3  Liquid nitrogen has the UN number 1977.

Oxygen family At this temperature, most gases that make up air become liquid. The liquid air is then allowed to evaporate. At a temperature of about −196°C (−320°F), nitrogen begins to boil off. When most of the nitrogen is gone, argon and neon also boil off, leaving an impure form of oxygen behind.

- (air). The air we breathe is about 80% nitrogen gas. So what we have here is liquid air. It took a really powerful refrigerator to make the air so cold that it turns into a liquid. Most gases turn into a liquid when they get cold enough.

Questions and Answers Under normal atmospheric pressure, nitrogen can exist as a liquid between the temperatures of 63 K and 77.2 K. (-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas. Since it is obtained from the atmosphere, liquid nitrogen is inexpensive and is rarely refrigerated. It is kept in insulated containers called Dewars and is allowed to boil away. Since it is boiling, most of the liquid nitrogen used in laboratories and in cryogenics shows is at a temperature of 77.2 K. Liquid nitrogen looks like boiling water. If you have never seen it, we have a picture of some posted on our site.

Liquid Nitrogen Temperature Answer: Liquid nitrogen is very cold! At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below this temperature, it freezes into solid nitrogen.

Nitrogen Nitrogen is a colorless odorless gas at normal temperature. It is normally attached to another nitrogen atom, making a nitrogen molecule (N2). The bond is very strong. That is why many explosives contain nitrogen. The bond is broken when the explosive is made. When it explodes the bond forms, releasing a lot of energy.

- Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is nonflammable and it will not support combustion. Nitrogen gas is slightly lighter than air and slightly soluble in water. It is commonly thought of and used as an inert gas; but it is not truly inert.

Why are the technicians use dry nitrogen instead of normal air to pressure test the pipes? Nitrogen is relatively cheap. A K size cylinder is less than $10.00 at most vendors. Air is about 79% nitrogen and 20% oxygen. When extracting oxygen for welding gas and medical use the water and other expensive gases are separated leaving dry nitrogen. Nitrogen has demand for dehydrating optical instruments and communication cables, but is still sold more on the basis of costs of inventory and transportation than on any intrinsic value.

Liquid nitrogen Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. It is a colorless clear liquid with a density of 0.807 g/ml at its boiling point (−195.79 °C (77 K; −320 °F)) and a dielectric constant of 1.43. Nitrogen was first liquefied at the Jagiellonian University on 15 April 1883 by Polish physicists, Zygmunt Wróblewski and Karol Olszewski.
