Additionally, cryogenic liquids such as liquid nitrogen have boiling points below that of oxygen and are capable of condensing atmospheric oxygen, resulting in a localized, oxygen-enriched environment ...

And while we always love to see that kind of content, this hop into the world of cryogenics and liquid oxygen production shows that [Shahriar] has other interests, too. Of course, to make liquid ...

The density of liquid oxygen = 1.1 g/cm 3 The density of gaseous oxygen = 0.0014 g/cm 3 State Distance between particles Density Density in g/cm 3 Solid Very close together High Solid iron = 7.8 ...

Liquid oxygen itself thus became available as a refrigerating agent, and afforded the means of cooling a tube containing any other gas to a temperature lower than ever; namely, about 211° below ...
