Physics:Expansion ratio
From HandWiki
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.[1] If a sufficient amount of liquid is vaporized within a closed container, it produces pressures that can rupture the pressure vessel. Hence the use of pressure relief valves and vent valves are important.[2]
The expansion ratio of liquefied and cryogenic from the boiling point to ambient is:
- nitrogen – 1 to 696
- liquid helium – 1 to 745
- argon – 1 to 842
- liquid hydrogen – 1 to 850
- liquid oxygen – 1 to 860
- neon – Neon has the highest expansion ratio with 1 to 1445.[3][4]
