Write a method to separate different gases from the air.

• Air is a homogeneous mixture of many gases. The components can be separated by the method of fractional distillation of liquid air.

• Air is first filtered and then compressed and cooled by increasing pressure and decreasing temperature to obtain liquid air.

• This liquid air is then warmed up slowly in a fractional distillation column.

• Different component gases of air get separated at different levels according to their boiling points.
