WebJan 14, 2024 · The rusting of steel is an example of an exothermic chemical reaction. The rusting of iron or steel is an oxidation reaction -- really just a slower form of combustion. While waiting around for rust to form wouldn't make for an interesting chemistry demonstration, there are ways to speed up the process. WebWhen heat is taken in by the system from the surroundings, a chemical reaction or physical change is said to be endothermic. An endothermic process causes the system to absorb heat from its surroundings, which causes the surroundings' temperature to drop. The letter ‘q’ stands for the amount of heat a process requires.
