How is Nitrogen isolated from liquid air?
Fractional distillation of liquid air:
Conclusion: Therefore using fractional distillation liquid air produces Nitrogen.
The correct increasing order of the boiling points of liquid oxygen, liquid argon and liquid nitrogen present in liquid air is :
(a) nitrogen, oxygen, argon (b) nitrogen, argon, oxygen
(c) argon, oxygen, nitrogen (d) oxygen, argon, nitrogen
