Have you ever wondered how hand warmers work? Well because of exothermic reactions which release energy in the form of heat, causing things like hand warmers to gradually become warm. 

 Exothermic reactions are a fundamental concept in the world of chemistry. They occur when energy is needed to break the bonds of the reactants when it’s less than the energy that is released, whatever excess energy is left gets released as heat making things warm. 

Exothermic reactions are everywhere around you. In everyday life we use things like hand warmers, which use an iron power it reacts with the oxygen in the air to produce heat helping us stay warm throughout the wintertime. 

By taking the time to explore different exothermic reactions, it allows us to appreciate the science behind the warmth that we receive from handwarmers. This topic is truly fascinating and helps connect simple chemistry to people’s everyday lives.
