Definition & Meaning
Endothermic and exothermic reactions are fundamental concepts in chemistry, describing how energy is absorbed or released during chemical reactions. An endothermic reaction is one that absorbs energy, usually in the form of heat, from its surroundings. This energy absorption leads to a decrease in temperature in the surrounding environment. Common examples include the melting of ice or the process of photosynthesis in plants. Conversely, an exothermic reaction releases energy, resulting in an increase in temperature of the surroundings. A classic example is combustion, such as burning wood or gasoline, where heat is released as a byproduct.
