eksotermiseksi

Eksotermiseksi refers to a chemical reaction that releases energy, usually in the form of heat. This release of energy means that the products of the reaction have lower enthalpy than the reactants. The term originates from Greek words "exo" meaning outside and "thermos" meaning heat.

In an exothermic process, the system's internal energy decreases as it transfers energy to the surroundings. This can be observed as a temperature increase in the environment where the reaction is taking place. Common examples include combustion reactions, such as burning wood or natural gas, where significant amounts of heat are generated. Another everyday example is the neutralization reaction between a strong acid and a strong base.

The energy released in an exothermic reaction is quantified by its enthalpy change, denoted as ΔH. For exothermic reactions, ΔH is negative, indicating a net loss of energy from the system. This energy can also be released as light or sound, although heat is the most common manifestation. Understanding exothermic reactions is crucial in various fields, including chemistry, engineering, and environmental science, for controlling reactions, designing energy-efficient systems, and predicting environmental impacts.
