For example, when the process is endothermic, the kinetic energy increases since the temperature increases, but remains constant at a phase change. However, during an exothermic process the kinetic energy decreases along with the temperature and during a phase change the energy and temperature will remain constant. The kinetic energy is opposite for each of the curves because as the kinetic energy decreases during the exothermic process causing the number of molecules of the products to decrease as they come closer. The potential energy remains constant for both graphs since the temperature either increases or decreases, while the kinetic energy increases for an endothermic process and decreases for an exothermic process. As the heating curve (graph A) is represented in the graph the difference in each of the phases can be seen through it like the cooling curve (graph B) where the graph represents very clearly the phases and their
