Why is liquid nitrogen used to fast freeze food instead of liquid oxygen? There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing.
Divers replace the nitrogen in their tanks with helium to remove that risk. Any potential gas we would want to use as a nitrogen replacement would have to be inert or mostly inert. Being inert means it wouldnât react or undergo chemical reactions within our body. However, even inert gases have a narcotic potential when breathed, and that potential directly corresponds to each elements mass.
