Handwarmers are an example of an exothermic reaction. They release heat into their surroundings. However, exothermic reactions don't always release heat, sometimes the energy is released as light.

An exothermic reaction releases energy in the form of light or heat to its surroundings, contrasting with endothermic reactions which absorb energy. The term "Exo" denotes "release," and "thermic ...

Tell students that an example of a very exothermic reaction is the combustion or burning of fuel like the gas in a kitchen stove. Even if students have seen the animation of the combustion of methane ...

IntroductionCommercial heat packs (containing iron and water, or supersaturated sodium acetate) and cold packs (various ammonium salts) can be used to show exo- and endothermicity.Heat packs that ...
