Detailed explanation-1: -Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.
Detailed explanation-2: -Combustion is a chemical process in which a substance reacts with oxygen and gives out energy. The energy released can be either in the form of heat or light or both. Rusting of iron is an exothermic process as heat is released during the process. Hence, it is a kind of slow combustion.
Detailed explanation-3: -combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
Detailed explanation-4: -Definition of combustion The chemical process in which a substance reacts with oxygen to give off heat is called combustion. Examples are ethane, wood, propane.
Detailed explanation-5: -Combustion refers to the process where a substance burns in the presence of Oxygen, giving off heat and light in the process.
