Liquid oxygen (LOX) is a cryogenic liquid having a freezing point of (−182.96 °C) and a boiling point of (−182.96 °C at 101.325 kPa. It has an expansion ratio of 1:861 under one standard atmosphere (100 kPa) and 20 °C. In other words, one liter of liquid oxygen can make 861 liters of gaseous oxygen.
Liquid oxygen is produced by the liquefaction of atmospheric air and the separation of oxygen from other gases such as nitrogen, argon, and other rare elements.
