Fractional Distillation - Oil Separation

The video explains the process of fractional distillation, which separates crude oil into useful components. Crude oil, a valuable mixture of liquids, is heated in an oil refinery to become gases. These gases are then fed into a fractionating column, where they condense at different temperatures. This process separates the oil into fractions like petrol, kerosene, and bitumen, each with specific uses such as fuel for cars, planes, and road construction.

What is the primary reason crude oil needs to be separated?

• To make it useful

• To make it less dense

• To make it lighter

• To make it more colorful

In the process of fractional distillation, what happens to crude oil first?

• It is frozen

• It is mixed with water

• It is heated

• It is cooled

What is the role of the fractionating column in fractional distillation?

• To compress the gases

• To add color to the gases

• To separate gases based on condensation points

• To mix the gases

Which fraction of crude oil is used as fuel for cars?

• Kerosene

• Bitumen

• Petrol

• Diesel

What is bitumen primarily used for after fractional distillation?

• Cooking

• Making plastics

• Building roads

• Fuel for planes
