Air is a mixture of nitrogen, oxygen and smaller amounts of many other substances. If air is filtered and cooled to low temperatures it becomes a mixture of liquids. Nitrogen gas and liquid oxygen can be separated from this ‘liquid air’ by fractional distillation. The table shows the boiling points of nitrogen and oxygen. Use your knowledge and understanding of fractional distillation, and the information given, to explain how nitrogen and oxygen can be separated from air.
