What Generalize the changes in thermal energy when matter increases in temperature and then change state?

When matter increases in temperature, its thermal energy rises as the kinetic energy of its particles increases, causing them to move more vigorously. As the temperature reaches a certain threshold, the matter may undergo a phase change, such as melting or boiling, during which thermal energy is absorbed or released without a change in temperature. This energy is used to overcome intermolecular forces, allowing the particles to transition to a different state, such as from solid to liquid or liquid to gas. Overall, the thermal energy of the system plays a crucial role in both heating and changing the state of matter.
