Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
For example, in 2012, a young woman in England had to have her stomach removed after ingesting a cocktail made with liquid nitrogen. [109] 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. In an incident on January ...

Liquid helium is used to cool superconducting magnets in modern MRI scanners. Noble gases have very low boiling and melting points, which makes them useful as cryogenic refrigerants . [ 82 ] In particular, liquid helium , which boils at 4.2 K (−268.95 °C; −452.11 °F), is used for superconducting magnets , such as those needed in nuclear ...
A supercritical fluid (SCF) is a substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid. [1] It can effuse through porous solids like a gas, overcoming the mass transfer limitations that slow liquid transport through such ...
Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
NEW Cooperative, Inc. in Red Oak notified officials Monday, March 11, that a valve on an aboveground tank storing liquid nitrogen fertilizer was left open all weekend, according to a March 28 news ...
A liquid nitrogen leak at a northeast Georgia poultry plant killed six people Thursday, with multiple others taken to the hospital, officials said. At least three of those injured at the ...
