This chemical process is called fractional distillation.
Air components are separated by fractional distillation.
Air can be separated into its components using methods like fractional distillation or air separation plants. These processes take advantage of the differences in boiling points and properties of the components of air (mainly nitrogen, oxygen, and argon) to separate them into pure form. The most common method involves cooling and compressing air to liquefy it, then allowing it to evaporate at different temperatures to collect the separate components.
The boiling points of the components are different, so when the liquid mixture of air is heated to a certain temperature, the component with a boiling point lower than this temperature will boil off and separate.
To condense oxygen from the air, you would have to cool the air to a temperature below the boiling point of oxygen, which is around -183 degrees Celsius. This process would separate the oxygen gas from the other components of air, allowing it to be collected as a liquid.
Cryogenic distillation of air is a method to obtain pure noble gases.
That would be a centrifuge.
A homogeneous mixture would be the hardest to separate because the components are evenly distributed at a molecular level, making it difficult to physically separate them.
because we would
Oxygen can be separated from liquefied air through a process called fractional distillation. This involves gradually heating the liquefied air to separate its components based on their boiling points. Since oxygen has a lower boiling point than other components in air, it will vaporize and can be collected as a gas while the other components remain liquid.
filtration or distillation
You would use a drainer to separate a suspension
One way is to liquify air using high pressure and low temperature, then fractional distillation to separate the air into its components, including nitogen.
