The liquid air has three components X,Y and Z whose boiling points are : `-186^(@)C,-183^(@)C and -196^(@)C,` respectively. When liquid air is fed into a tall fractional distillation column from near its bottom and warmed up slowly:
(a) Which component will be collected from near the bottom of the fraction distillation column ? Why ?
(b) Which component will be collected from the top part of the fractional distillation column? Why ?
(c) Which component will be collected from the middle part of the fractional distillation column? Why ?
(d) What could the component X, Y and Z be?

Answer

(a) Y ; It has the highest boiling point of, `-183^(@)C` (b) Z; It has the lowest boiling point of, `-196^(@)C` (c ) X; It has a boiling point of, `-186^(@)C` which is lower than that of Y but higher than that of Z (d) X is liquid argon ; Y is liquid oxygen ;Z is liquid nitrigen
