Liquid nitrogen is a form of the element nitrogen that's cold enough to exist in a liquid state and is used for many cooling and cryogenic applications. Here are some facts about liquid nitrogen and crucial information about handling it safely.
The liquid, which has a tremendously low temperature, is elaborated on Facts about Liquid Nitrogen.It has the boiling point of -320 degrees F or -195.79 degrees C. It has the density of 0.807 gram per ml.
Interesting Nitrogen Facts: Nitrogen is believed to be the seventh most abundant element in the universe. At normal pressure, nitrogen liquifies at 77 K (-195.79 °C) and freezes at 63 K (-210.01 °C). Liquid nitrogen boils at -195.8 degrees Celsius. Due to its volatility, it is a fairly rare element on Earth, remaining as a gas in the atmosphere.
Nitrogen is a fascinating element with many unique properties and uses related to fertilizer, dynamite, medical anesthetic and even car racing. Read interesting facts about the nitrogen atom, liquid nitrogen, nitrous oxide, nitric acid, nitroglycerin and much more.
In our last article on Nitrogen Facts, we didn’t cover everything.For instance, we skipped the Nitrogen Cycle and of course, we didn’t mention enough about liquid Nitrogen. So, here we are, with another set of Nitrogen fun facts that will help you with your homework or will simply help you gain some knowledge.
Liquid nitrogen is nitrogen at a very low temperature. It is usually produced by a process known as fractional distillation of air. At atmospheric pressure (normal pressure) nitrogen boils at −196 °C (77 K; −321 °F). Nitrogen was first made into a liquid at Jagiellonian University on 15 April 1883.
The nitrogen turns into a liquid at a different temperature than the oxygen. It can also be made by heating certain chemical compounds, such as sodium azide. Uses. File:Nitrogen.ogv Nitrogen is an element is used to prevent things from reacting with the oxygen in the air.
Top 5 Facts: Liquid nitrogen. by How It Works Team · 04/10/2010. Below are five uses for any spare liquid nitrogen you might have lying around. Making ice cream. Ice cream frozen with liquid nitrogen is smooth, creamy, light in texture and a litre can be made in 3 seconds. Fans of this technique include world-class chef Heston Blumenthal.
Liquid nitrogen is frequently used as a refrigerant, for instance, to store sperm, eggs and other cells used in medical research or fertility clinics, according to the Royal Society of Chemistry.
Liquid nitrogen is a cryogenic fluid, capable of freezing skin on contact. While the Leidenfrost effect protects skin from very brief exposure (less than one second), ingesting liquid nitrogen can cause severe injury. When liquid nitrogen is used to make ice cream, the nitrogen vaporizes.
