Any reaction categories into exothermic and endothermic based upon change in enthalpy of reaction. If difference in enthalpy of product and reactant comes positive value then it is termed as endothermic and if it is negative value then exothermic reaction. Usually, vaporisation is considered as exothermic due to release in energy.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Exothermic/endothermic is a process not a feeling.
It is an endothermic process.
endothermic
Dissociation is an endothermic process.
Fission is an exothermic process.
endothermic reaction a positive enthalpy.
Breaking bonds produces energy making it an exothermic process.
It is an endothermic process.
Exothermic
I suppose that is an endothermic process.
Anions are not associated with either exothermic or endothermic processes on their own. The classification of a process as exothermic or endothermic depends on the overall energy change of the reaction in which the anion is involved.
