Fractional distillation refers to taking different volatile substances off at different temperatures. To fractionally distill air the differences in boiling points of its two main components oxygen and nitrogen are used.
Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide.
Nitrogen boils at −196 °C
Oxygen boils at −183 °C
Argon boils at -186.0 °C
Carbon dioxide sublimes at -78.5 ºC
If the air mixture is cooled to -200 ºC then theoretically all the gases are liquids. As the temperature is carefully increased then nitrogen would boil off at -196 ºC leaving the other gases as still liquid. The nitrogen thus is collected. As the temperature is slowly increased past -183 ºC the oxygen could be collected etc.
Alternatively, the temperature could be slowly decreased and the solid carbon dioxide collected when the temperature drops below -78.5 ºC. Next liquid oxygen is collected at just below -183 ºC leaving the other components of air still as gases, and so on...
Nothing, because all the components of air are human friendly.
By fractional distillation of liquid air.
fractional distillation this is a liquid with the lowest boiling point
all nobel gasses are obtained by fractional distillation of liquid air.
The answer is,Fractional distillation is based upon the boiling points of the liquid so that we can identify the liquid when there is a plateau on the graph (when the temperature is the same or close together).
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
