Crude oil is a miscible mixture of liquids that has many uses. During the refining process, it is separated and used to produce aviation fuel, diesel fuel, and gasoline.
How should scientists separate crude oil based on its physical properties?
They should warm up the mixture to cause one of the substances to melt out of the it; then, they should freeze it in a separate container.
They should leave the mixture alone and let it settle so that the parts of the crude oil separate; then, they should decant the parts.
They should shake the mixture to make the substances separate based on the different sizes of their particles; then, they should filter it.
They should boil the mixture so that one of the substances evaporates out of it; then, they should condense it in a separate container.
