Oxygen, becuase it has higher boiling point compared to other gases ( -183c ) .

*Gases present in air.

AIR IS SEPARATED INTO ITS COMPONENT GASES IN FOLLOWING STEPS:-
1)*THE AIR IS FILTERED TO REMOVE DUST THEN WATER VAPOUR AND CARBON DIOXIDE ARE REMOVED FOR FURTHER ADVANCES.
2)*THE PROCESS OF CIMPRESSION,COOLING AND RAPID EXPANSION OF AIR IS REPEATED AGAIN AND AGAIN MAKING THE AIR MORE COOLER.
3)*THE LIQUID AIR IS FED INTO A TALL FRACTIONATING COLUMN FROM NEAR ITS BOTTOM:-
SO FRIENDS NOW FIRSTLY
1)*LIQUID NITROGEN WITH A BOILING POINT OF -196?C BOILS FIRST TO FORM NITROGEN GAS
2)*THEN LIQUID ARGON TO FORM ARGON GAS WITH A BOILING POINT OF -186?C
3)*THE LAST LIQUID OXYGEN TO FORM OXYGEN GAS WITH BOILING POINT OF -183?C
