The word cryogenics stems from Greek and means "the production of freezing cold"; however, the term is used today as a synonym for the low temperature state. It is not well defined at what point on the temperature scale refrigeration ends and cryogenics begins, but most scientists assume it starts at or below -150°C. The National Institute of Standards and Technology at Boulder, Colorado has chosen to consider the field of cryogenics as that involving temperatures below 180°C. This is a logical dividing line, since the normal boiling points of the so called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below 180°C while the Freon refrigerants, hydrogen sulfide, and other common refrigerants have boiling points above 180°C.
