| fractional distillation | process based on boiling point used to separate crude oil |
| as length of carbon chain increases | viscosity and boiling point increase |
| as length of carbon chain decreases | flammability and volatility decrease |
| coal | comes mainly from fossilised plants |
| crude oil | usuallu formed from dead sea animals and plants |
| hydrocarbon | a compound that contains only carbon and hydrogen |
| alkane | a compound that contains carbon and hydrogen only with single bonds only |
| catalytic cracking | process used to break long chain compounds into more useful, shorter ones |
