Here's how it works:

1. Heating: The mixture is heated, causing the component with the lower boiling point to vaporize first.

2. Vaporization: The vapor rises and is collected separately.

3. Condensation: The vapor is cooled, causing it to condense back into a liquid.

4. Collection: The condensed liquid, now separated from the original mixture, is collected.

This process can be used to separate various mixtures, such as:

* Salt water: Water boils at a lower temperature than salt, allowing the water to be evaporated and collected separately.

* Ethanol and water: Ethanol has a lower boiling point than water and can be separated by distillation.

* Crude oil: Distillation is used to separate different components of crude oil based on their boiling points, producing gasoline, diesel, kerosene, etc.
