Noble gases A, B, C, D, E are passed through Dewar's flask at-100^@C A

1.	Noble gases A, B, C, D, E are passed through Dewar's flask at-100^@C A, C & E gases are adsorbed. Unadsorbed gases B, D are passed through another Dewar's flask at-180^@C. Gas B is adsorbed. The Dewar's flask al-100^@C is put in contact with another Dewars flask al-193^@C. The gas Eis diffused in it. Finally A & C are seperated by warming the flask from-100^@C w -90^@C. Ilere 'C' comes out He and Ne gases respectively are
Answer» Ne Ar Kr Xe Solution : `He, Ne underset("Deewars flask "-180^@C)overset("another")to`Ne is absorbed. He is unadsorbed, He has WEAK vander wall forces. Charcoal - 1 contains Ar, Kr, Xe is cooled to `-180^@C`. At this TEMP. Ar. Gets LIQUIFIED while Kr & Xe remain adsorbed. (E) = Ar, (A)= Kr,(C )= Xe
