Walk-In Take out notebook, folder, pencil box. Copy the question and answer in sentences. Is a battery an example of chemical energy or electrical energy? Explain!
Answer A battery is a form of CHEMICAL ENERGY. It contains acids and other chemicals that take part in chemical reactions. These release electrons, that can flow in a wire as an electric current, which enables a device that runs on batteries to be able to work.
