Is the burning of fuel in a car combustion?

Yes, the burning of fuel in a car is combustion. Combustion is a chemical reaction that involves the rapid oxidation of a fuel with an oxidizer, usually oxygen. This reaction releases heat energy and often leads to the formation of flames. When you put your foot on the gas pedal of your car, you allow more fuel to flow into the engine where it mixes with oxygen from the air. This mixture is then ignited by a spark plug, causing it to combust and rapidly expand. This expansion forces the pistons in the engine to move, which in turn drives the wheels of your car.
