The expansion ratio of a liquefied and cryogenic substance is the volume of a given amount of that substance in liquid form compared to the volume of the same amount of substance in gaseous form, at room temperature and normal atmospheric pressure.
- nitrogen 1 to 696
- liquid helium 1 to 757
- argon 1 to 847
- liquid hydrogen 1 to 851
- liquid oxygen 1 to 860
- Neon has the highest expansion ratio with 1 to 1445.
