heat of combustion

The heat of combustion is the amount of heat released when a substance burns. This is a type of heat of reaction, which is the heat absorbed or released during any chemical reaction. If a reaction releases heat, it's called exothermic. Combustion reactions are typically exothermic and are initiated by heat, light, or sparks, requiring the substance to reach its ignition temperature.12

Combustion is a complex chemical process with practical applications in heating devices, industry, and explosives. Key combustion reactions involve oxygen with hydrogen, carbon monoxide, and hydrocarbons, producing water and other compounds. Understanding these reactions is crucial for designing efficient industrial processes and controlling combustion phenomena.34512
