Air is a. mixture and can be separated into its compound by dash
Answers
Answer:
Air is a homogeneous mixture and can be separated into its components by fractional distillation. ... The air is compressed by increasing the pressure and is then cooled by decreasing the temperature to get liquid air.
Explanation:
1.The liquid air undergoes a process called fractional distillation. Fractional distillation uses the different boiling points of the main elements of air. As the liquid air is heated, the elements change from liquid to gas and separate from one another. Pump air through a filter to remove dust and other contaminants.
2.Air is a mixture not a compound for following reasons: 1) air can be separated into it constitutes like oxygen, nitrogen etc. by physical process of fractional distillation. 2) error shows the properties of all the gases present in it.

How can we obtain different gases from air?
Answer: Air is a homogeneous mixture and can be separated into its components by fractional distillation. The flow diagram given under shows the steps of the process.
If we want oxygen gas from air, we have to separate out all the other gases present in the air. The air is compressed by increasing the pressure and is then cooled by decreasing the temperature to get liquid air. This liquid air is allowed to warm-up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points
