Why hydrogen gas is liquefied first than helium gas?

Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.


Will all the real gas be liquefied at high pressure?

No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.


Which gas was the last to be liquefied?
