==In chemistry== [[File:22. Ендотермна реакција.ogv|thumb|right|The formation of [[barium thiocyanate]] from [[ammonium thiocyanate]] and [[barium hydroxide]] is so endothermic that it can freeze a [[beaker (lab equipment)|beaker]] to wet [[styrofoam]]]] Due to bonds breaking and forming during various processes (changes in state, chemical reactions), there is usually a change in energy. If the energy of the forming bonds is greater than the energy of the breaking bonds, then energy is released. This is known as an exothermic reaction. However, if more energy is needed to break the bonds than the energy being released, energy is taken up. Therefore, it is an '''endothermic reaction'''.<ref>{{Cite web |title=Exothermic & Endothermic Reactions |url=https://highschoolenergy.acs.org/content/hsef/en/how-can-energy-change/exothermic-endothermic.html |access-date=2021-04-11 |website=Energy Foundations for High School Chemistry |publisher=American Chemical Society}}</ref>
