Question

a teacher makes the following statement. \gasoline boils at a relatively low temperature (about 150°c). the kerosene is removed at around 200°c, followed by diesel oil at 300°c and fuel oil at around 370°c.\ what topic is the teacher most likely talking about? distillation of a mixture filtration of a pure substance evaporation of a mixture sorting of a pure substance

Explanation:

Distillation separates components of a mixture based on different boiling - points. The teacher is describing separation of different oils (components of a mixture) at different temperatures, which is characteristic of distillation. Filtration separates solids from liquids in a pure substance context which is not relevant here. Evaporation is mainly about changing a liquid to a gas without separation based on boiling - points like this. Sorting of a pure substance is not related to these temperature - based separations.

Answer:

distillation of a mixture
