Understanding Crude Oil and Fractional Distillation

What is crude oil primarily composed of?

• Hydrocarbons

• Nitrogen and sulfur

• Only oxygen and hydrogen

• Carbon dioxide and water

How is crude oil formed?

• By mechanical compression of rocks

• Through decomposition of organic materials under high pressure and temperature

• From volcanic activity

• Through photosynthesis

Why are fossil fuels considered non-renewable?

• They take millions of years to form

• They are unlimited

• They can regenerate quickly

• They are primarily made of renewable biomass

What is the purpose of heating crude oil in fractional distillation?

• To increase its density

• To convert it into a gaseous state

• To purify it directly

• To reduce its volume

At what point do the hydrocarbons with the highest boiling points condense in the fractionating column?

• At the top where it is coolest

• Near the middle of the column

• At the bottom where it is hottest

• Outside the column

What are the uses of bitumen?

• To surface roads

• In food industry

• In jet engines

• For electrical insulation

Which hydrocarbon is used in cars?

• Lubricating oil

• Kerosene

• Bitumen

• Diesel

What is the process called that breaks down longer chain hydrocarbons into smaller ones?

• Condensation

• Cracking

• Filtration

• Fermentation

What is the primary use of petrochemicals?

• As raw materials in the petrochemical industry

• In agricultural fertilizers

• For water purification

• In renewable energy production
