Lubov Fominskaja [6]

The gas particles leaving the car exhaust show the process of combustion.

<h3>What is the process of combustion?</h3>

Combustion refers to a chemical process in which a substance reacts with oxygen to give off heat. The original substance is known as the fuel, whereas the source of oxygen is known as the oxidizer. The fuel can be present in solid, liquid, or gas, but for an airplane, the fuel is usually a liquid form. Combustion also called burning that is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine, the ignition and combustion of the fuel occurs within the engine. The engine converts the energy from the combustion process to work.

So we can conclude that the car releases gases due to the process of combustion.
