These are examples of chemical energy....

• A fire, drying clothes, cooking food

• A hammer, windmill, & wrecking ball

• The sun, visible light & x-ray

• A battery, digestion & burning fuel

When water falls through a dam and turns a turbine connected to a generator, electricity is produced. This electricity is often used to light our homes and offices. Which of the following shows the energy transformations that occurs?

• electrical → light → mechanical
