What form of energy is produced by the sun?

Back

The sun produces light energy and thermal (heat) energy.

Front

What is sound energy?

Back

Sound energy is a form of energy that is produced when an object vibrates, creating waves that travel through air or other mediums.

What happens to thermal energy when a substance melts?

Back

When a substance melts, thermal energy is absorbed, causing the particles to move more freely and transition from a solid to a liquid state.
