option A. Explanation- Higher the critical temperature of a gas, more easily it is liquefied. Hence, the correct order of liquefaction is He is an noble gases so it has least crit...

A difference in critical temperatures among gases means that some gases are easier to liquefy than are others. The critical temperature of carbon dioxide is high enough so that it ...
