What is a change in the arrangement or energy of a materials particles?

A change in the arrangement or energy of a material's particles refers to a phase change or a thermal process, where particles may transition between solid, liquid, or gas states. This change often involves the absorption or release of energy, which affects the kinetic energy and interactions between particles. For example, heating ice causes its particles to gain energy, resulting in a transition to liquid water. Conversely, cooling water can lead to the formation of ice as particles lose energy and arrange into a solid structure.
