Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the particles. Following are the critical temperatures of some gases.

Gases	H2	He	O2	N2
Critical temperature in Kelvin	33.2	5.3	154.3	126

From the above what would be the order of liquefaction of these gases? Start writing the order from the gas liquefizing first

• A

  ${\mathrm{H}}_2,\mathrm{He},{\mathrm{O}}_2,{\mathrm{N}}_2$

• B

  $\text{ He, }{\mathrm{O}}_2,{\mathrm{H}}_2,{\mathrm{N}}_2$

• C

  ${\mathrm{N}}_2,{\mathrm{O}}_2,\mathrm{He},{\mathrm{H}}_2$

• D

  ${\mathrm{O}}_2,{\mathrm{N}}_2,{\mathrm{H}}_2,\mathrm{He}$
