WebApr 3, 2024 · A term used to describe a reaction or process that releases energy in the form of heat. Sometimes the term is applied to processes that release other forms of energy, such as electrical energy, sound, or light. Example: Combustion of wood Cite this Article WebAn exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”. …
