When something is hot it has thermal energy. On the other hand when a substance is cool it doesn’t have “thermal energy” because it isn’t hot.

Answer:When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
