Combustion is a chemical process in which a substance reacts rapidly with oxygen to release energy in the form of heat and light. It is one of the most important processes of energy conversion used in daily life and in many industrial applications. Fuels such as coal, wood, natural gas, petrol, diesel, and biomass undergo combustion to produce useful energy. During this process, the chemical energy stored in the fuel molecules is transformed into thermal energy through chemical reactions. For combustion to occur, three essential elements are required: fuel, oxygen, and heat. These three components together form what is commonly known as the fire triangle. Fuel is the substance that burns, oxygen supports the burning process, and heat provides the initial energy needed to start the reaction. When these three elements are present in proper proportions, combustion takes place and energy is released. The process of combustion begins when a fuel is heated to its ignition ______ _____ ________ ________ __________ _______ ________ _____.
