1the first step in fractional distillation for petrol
- A
longer chained molecules stay at the bottom while shorter chained molecules vaporise and go to the top - B the oil is heated to 350°C
- Cthey are collected in different fractions
- D hydrocarbons that have low boiling points are collected at the top and hydrocarbons with high boiling points are collected near the bottom
- E they cool and condense once reaching there boiling points
- A
