i am in 8th grade k12 science pls help What is happening to the energy symbols on the iron block as it is cooled?

Sagot :

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.

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.
