Analogy
Crude oil is like changing a recipe: the particles, amounts and conditions decide what product you can make.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Crude oil is a mixture of hydrocarbons.
Fractional distillation separates hydrocarbons by boiling point.
Shorter hydrocarbons are more volatile and more flammable.
