Thermal decomposition - Wikipedia

Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback loop is created …

What Is Thermal Decomposition? | Reference

Thermal decomposition is a chemical reaction where heat causes one substance to break into two or more different substances. The heat is used to break down the bonds holding the atoms of the original molecules together, so the reaction usually consumes more heat energy than it releases.
