the answer is correct, the air would be liquified and then factional distillation would be used to separate the gases
fractional distillation depends on boiling point
The property used in the industrial preparation of nitrogen and oxygen from air is the difference in boiling points between these gases. This property is exploited in a process called fractional distillation, also known as cryogenic distillation.
Air is a mixture of various gases, including nitrogen and oxygen. In the fractional distillation process, air is cooled to very low temperatures until it becomes a liquid. Because nitrogen has a slightly lower boiling point than oxygen (-195.8°C for nitrogen and -183.0°C for oxygen), when the air is slowly warmed, nitrogen will evaporate first, leaving liquid oxygen behind. This separation is based on the difference in boiling points of the gases and allows for the industrial-scale production of nitrogen and oxygen from air.
yeah the property used in the preparation of nitrogen and oxygen from Air can be determine by their boiling point reasons is because fractional distillation can be used for two substances having a closer boiling point
