📝 Key Facts: Crude Oil
- Crude oil = mixture of many different hydrocarbons
- Hydrocarbon = molecule containing hydrogen and carbon ONLY

- It's a physical process — no chemical bonds broken
- Smaller molecules = lower boiling point, more flammable, less viscous
- Larger molecules = higher boiling point, less flammable, more viscous
- Crude oil is a finite, non-renewable resource
