Note references: Specific Heat and Heat Capacity, Enthalpy, Phase Changes and Calorimetry. When a solid dissolves in water, the process always has a energy change associated with it. Examples exist for both endothermic and exothermic heats of solution. However, the dissolving process itself is really a two-step process. The size of a fluorine atom is very small as compared to a chlorine atom. Therefore, the repulsion between electrons in the outer most shell of the two atoms in a fluorine molecule is much greater than that in a chlorine molecule.
