Gasoline
In short
A flammable liquid fuel made from petroleum used to power internal combustion engines. It is commonly known as petrol in British English.
In plain words
It is a clear, yellowish liquid taken from crude oil. People put it in cars and motorbikes to make the engines run. It is highly flammable and needs careful handling.
A simple example
A driver pulls into a service station to fill their car's tank with unleaded fuel so they can continue their journey.
Why it matters
It is one of the most important energy sources for global transport. Most modern cars rely on it to move people and goods around the world.
Easy to mix up
Do not confuse it with diesel, which is a different type of fuel used in larger engines.
