Eksotermilises

Eksotermilises refers to a chemical reaction that releases energy, usually in the form of heat, into its surroundings. This is in contrast to endothermic reactions, which absorb energy from their surroundings. The term "eksotermilises" is derived from Greek words: "exo" meaning "outside" and "thermos" meaning "heat." Therefore, an eksotermilises reaction is one where heat goes outside the system.

In an eksotermilises reaction, the energy stored in the chemical bonds of the reactants is greater than the energy stored in the chemical bonds of the products. This difference in energy is released during the reaction. The change in enthalpy (ΔH) for an eksotermilises reaction is negative, indicating that the system loses energy to the surroundings.

Common examples of eksotermilises reactions include combustion, where fuel burns and releases heat and light, and neutralization reactions between acids and bases, which often produce a noticeable temperature increase. The rusting of iron is also an eksotermilises process, albeit a slow one. The energy released in these reactions can be harnessed for various purposes, such as heating homes or powering engines. Understanding eksotermilises reactions is fundamental in chemistry and has practical applications across many scientific and industrial fields.
