Kerosene, also known as paraffin or kerosine, is a combustible hydrocarbon liquid derived primarily from petroleum. It is widely utilized as a fuel in various applications, including aviation, heating, and cooking.
In many parts of the world, particularly in developing countries like the Philippines, kerosene remains a common fuel for cooking and heating. It is often used in kerosene lamps and portable heaters.
Kerosene can exist in a gaseous state, but under normal atmospheric conditions, it is typically a liquid.
