eksotermisissa

Eksoterminen is a Finnish word that translates to "exothermic" in English. It describes a process or reaction that releases energy, typically in the form of heat, into its surroundings. This is in contrast to endothermic processes, which absorb energy from their surroundings.

In chemistry, exothermic reactions cause the temperature of the immediate environment to increase. A common example is combustion, where the burning of fuel releases a significant amount of heat and light. Other examples include the neutralization reaction between a strong acid and a strong base, and the process of setting concrete. The energy released in an exothermic reaction comes from the breaking and forming of chemical bonds. When the bonds formed in the products are stronger (more stable) than the bonds broken in the reactants, there is a net release of energy.

The term "eksoterminen" can also be applied more broadly to physical processes. For instance, when a gas condenses into a liquid, it releases latent heat, making the condensation process exothermic. Similarly, certain phase transitions, like freezing, are exothermic. Understanding exothermic processes is crucial in various fields, including chemical engineering, thermodynamics, and even in everyday applications like hand warmers, which utilize controlled exothermic chemical reactions.
