is about the concrete effect. For self-maintained thermal homeostasis, see Endotherm.
In thermodynamics, the appellation endothermic describes a action or acknowledgment in which the arrangement absorbs activity from its ambience in the anatomy of heat. The appellation was coined by Marcellin Berthelot from the Greek roots endo-, acquired from the chat "endon" (бј”ОЅОґОїОЅ) acceptation "within" and the basis "therm" (ОёОµПЃОј-) acceptation "hot." The advised faculty is that of a acknowledgment that depends on demography in calefaction if it is to proceed. The adverse of an endothermic action is an exothermic process, one that releases, "gives out" activity in the anatomy of heat. Thus in anniversary appellation (endothermic & exothermic) the prefix refers to area calefaction goes as the acknowledgment occurs.
The abstraction is frequently activated in concrete sciences to, for example, actinic reactions, area thermal activity (heat) is adapted to actinic band energy.
Endothermic (and exothermic) assay alone accounts for the enthalpy (∆H) change of a reaction. The abounding activity assay of a acknowledgment is the Gibbs chargeless activity (∆G), which includes an anarchy (∆S) and temperature appellation in accession to the enthalpy. A acknowledgment could be a Spontaneous action at a assertive temperature if the articles accept a lower absolute chargeless activity (an exergonic reaction) even if the enthalpy of the articles is higher. Anarchy and enthalpy are altered terms, so the change in entropic activity could affected an adverse change in enthalpic energy.
