Cryogenic gas definition
In physics, cryogenics is the production and behaviour of materials at very low temperatures. The 13th IIR International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (or –153 °C) to … See more Cryogenics The branches of engineering that involve the study of very low temperatures (ultra low temperature i.e. below 123 Kelvin), how to produce them, and how materials behave at those temperatures. See more The word cryogenics stems from Greek κρύος (cryos) – "cold" + γενής (genis) – "generating". See more Some applications of cryogenics: • Nuclear magnetic resonance (NMR) is one of the most common methods to determine the physical and chemical properties of atoms by detecting the radio frequency absorbed and subsequent relaxation of nuclei … See more There are various cryogenic detectors which are used to detect particles. For cryogenic temperature measurement down to 30 K, Pt100 sensors, a resistance temperature detector (RTD), are used. For temperatures lower than 30 K, it is necessary to use a See more Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. Liquid nitrogen is the most commonly … See more Cryogenic cooling of devices and material is usually achieved via the use of liquid nitrogen, liquid helium, or a mechanical cryocooler (which uses high-pressure helium lines). … See more • Absolute zero • Coldest temperature recorded on Earth • Cryogenic grinding See more WebFor our purposes, a cryogenic liquid is defined as any liquid with a normal boiling point below ‐150°C (123K). 748 694 Gas (abbreviation) Boiling Point (K) Expansion Ratio Helium (LHe) 4.22 Nitrogen (LN2) 77.4 At the NCNR, by far the most commonly used cryogens are nitrogen and helium

WebFeb 2, 2011 · It is generally agreed that cryogenic fluids are those whose boiling points (bp) at atmospheric pressure are about 120 K or lower, although liquid ethylene with its boiling point of 170K is often included. A … Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in machinery that operates in space (e.g. rockets and satellites) where ordinary fuel cannot be used, due to the very low temperatures often encountered in space, and the absence of an environment that supports combustion (on Earth, oxygen is abundant in the atmosphere, whereas human-explorable space is a vacuum where oxy…
