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",H_(2),He,O_(2), N_(2)),("Critical temperature in Kelvin",33.2,5.3,154.3,126):}`
From the above data what would be the order of liquefaction of these gases? Start writing the order from the gas liquefying first.

Options

A. `H_(2), He, O_(2) , N_(2)`
B. `He, O_(2) , H_(2) , N_(2)`
C. `N_(2, O_(2) , He , H_(2)`
D. `O_(2) , N_(2) , H_(2) , He `

Answer

D

Explanation

Higher the critical temperature,more easily is the gas liquefied. Hence order of liquefication `: O_(2) , N_(2) , H_(2) , He`.
