Fractional distillation of crude petroleum separates it into various products mainly based on differences in what property?

Explanation

Fractional distillation separates crude petroleum into different useful products, such as petrol, kerosene, diesel, and lubricating oil, based primarily on differences in their boiling points. The crude oil is heated in a tall fractionating column, and as vapors rise, different fractions condense back into liquid at different heights corresponding to their specific boiling ranges. Lighter fractions with lower boiling points, like petrol, are collected nearer the top, while heavier fractions condense lower down. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
