Answer:

The expansion ratio of a liquefied and cryogenic substance is the volume of a given amount of that substance in liquidform compared to the volume of the same amount of substance in gaseousform, at room temperature and normal atmospheric pressure.

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.

The expansion ratio of liquefied and cryogenic from the boiling point to ambient is:

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.

I hope you have understood this
