Cryogenics - Wikipedia
In physics, cryogenics is the production and behaviour of materials at very low temperatures.A person who studies elements that have been subjected to extremely cold temperatures is called a cryogenicist.. It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins, but scientists assume a gas to be cryogenic if it can be liquefied at or below −150 ...
