In this video, you will learn all about Fuels.
Any substance that is used to produce heat and energy is called a fuel. Fuels are used for:
• cooking food
• running vehicles
• generating electricity
• running machines in factories.
Some fuels occur naturally while others are produced artificially.
Fuels like coal, petroleum, and natural gas occur freely in nature. They are also known as fossil fuels because they are formed by the decomposition of dead and decayed plants and animals buried deep inside the layers of earth, millions of years ago.
