Gases posses 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 temperature for a gas, more is its ease of liquifaction. Therefore, the given order is correct.
