Understanding Crude Oil and Fractional Distillation

What is crude oil primarily composed of?

• Hydrogen and carbon

• Carbon and nitrogen

• Hydrogen and oxygen

• Oxygen and sulfur

What is the main purpose of fractional distillation in crude oil processing?

• To convert hydrocarbons into water

• To separate hydrocarbons based on boiling points

• To increase the viscosity of crude oil

• To reduce the carbon content in crude oil

Which fraction obtained from crude oil is used as fuel for aircraft?

• Bitumen

• Petrol

• Kerosene

• Diesel

What is the characteristic of hydrocarbons at the top of the fractionating column?

• They are highly viscous

• They have long chains and high boiling points

• They have short chains and low boiling points

• They are solid at room temperature

Which fraction of crude oil is used for road surfacing?

• Diesel

• Petroleum gas

• Bitumen

• Kerosene

Why is crude oil considered a finite resource?

• It is constantly replenished by the ocean

• It takes millions of years to form

• It is made from renewable materials

• It is produced rapidly by natural processes

What is one of the main research areas related to crude oil?

• Discovering renewable sources of hydrocarbons

• Enhancing its color and smell

• Developing methods to make it non-flammable

• Finding ways to increase its viscosity
