What is fractional distillation?
A process used to seperate substances with different boiling points
What fractional distillation used for?
To seperate crude oil into fractions
What is a fraction?
A fraction is a group of hydrocarbons all with boiling points within a specific range
What is a fraction?
A fraction has specific uses and names
What do fractions differ in?
