WebThe reaction system to be considered is only the water, and if water is cooling down, it must be releasing energy in an exothermic process. Sweating (evaporation) is an endothermic reaction. Wet skin feels cool in a breeze because the evaporative reaction of the water absorbs heat from the surroundings (skin and atmosphere). WebPotential energy is stored energy and results from such interactions as: - repulsion between nuclei; - attraction of nuclei and electrons; - bond vibration and rotation; - electron repulsion. We can show energy changes during a chemical reaction using energy profiles.
