Question 3

Question
Complete these stages of the Fractional Distillation of Crude Oil: Crude oil is vaporised at [blank_start]350[blank_end]C. Crude oil goes into the Fractionating [blank_start]Column[blank_end] and rises up through it. As the crude oil ascends, it cools and the various fractions are drawn off according to their boiling points. [blank_start]Larger[blank_end] fractions don't evaporate at all but run out of the bottom. [blank_start]Smaller[blank_end] fractions are drawn off as [blank_start]gases[blank_end] out of the top of the column.
