* Water and Ethanol: Ethanol has a lower boiling point than water, so when you heat the mixture, the ethanol will evaporate first. The evaporated ethanol can then be condensed back into a liquid and collected separately.
* Crude Oil: Crude oil is a complex mixture of hydrocarbons. Different hydrocarbons have different boiling points. By gradually heating the crude oil, different components can be separated and collected at different temperatures. This is how gasoline, kerosene, and diesel fuel are produced.
* Saltwater: Water has a lower boiling point than salt. By heating saltwater, the water will evaporate and leave the salt behind. The evaporated water can be condensed and collected.
Key Point: The effectiveness of distillation depends on the difference in boiling points between the liquids. The larger the difference, the easier it is to separate them.
