What term describes a chemical reaction that releases heat energy into its surroundings, such as combustion?

Explanation

An exothermic reaction is a chemical reaction that releases energy, usually in the form of heat, into its surroundings as it proceeds, often causing a noticeable temperature increase nearby. Common examples include combustion reactions, like burning wood or fuel, as well as many everyday reactions like the setting of certain types of glue or cement. The energy released in an exothermic reaction comes from the chemical bonds within the reactants, which contain more stored energy than the bonds within the resulting products.
