Explain how nitrogen oxygen argon are separated from air

1.	Explain how nitrogen oxygen argon are separated from air
Answer» These gases are seperated by the process of fractional distillation.In fractional distillation first the is comressed by increasing the temperature and is then cooled by decreasing the temperature to get liqid air.The liquid air is allowed to warm up in fractional distillation column.Here diferrent gases get seperated at diferrent heights accoring to their boiling points.
