Vedclass · Answer

(C) The noble gases are separated from a mixture by using coconut charcoal at different temperatures.This method relies on the principle of selective adsorption,where the extent of adsorption on coconut charcoal increases with the increase in the atomic weight of the noble gases.Helium $(He)$,having the lowest atomic weight,is adsorbed the least,whereas Xenon $(Xe)$,having the highest atomic weight,is adsorbed the most strongly.By varying the temperature,the gases can be desorbed sequentially,allowing for their separation.
