A battery converts what type of energy to another?

• sound to kinetic
• light to heat
• mechanical to electrical
• chemical to electrical

What is sound energy?

• Sound energy comes from vibrations moving through something. Solids, liquids, and gases all transmit sound as energy waves.

• The energy of objects in motion.

• The space between molecules when temperature is increased.
