What energy transformation do batteries perform?

A. stored electrical - -> kinetic - -> electrical

B. chemical - -> electrical

C. stored heat - -> electrical

D. heat - -> mechanical - -> electrical

B) chemical - -> electrical

Explanation:

Chemicals are stored in batteries with led metal to give positive and negative charges which produce electricity when the circuit of the battery is closed

Answer: Option B) chemical - -> electrical

Explanation:

Batteries convert their stored chemical energy into electrical energy in order to power appliances.

So, the conversion of chemical energy to electrical energy explains how energy is conserved in nature, such that energy is neither created nor destroyed.
