Question

dry cell batteries transform __________ into __________ by moving positive and negative ions
a chemical energy into kinetic energy
b chemical energy into electrical energy
c potential energy into electrical energy
d electrical energy into mechanical energy

Explanation:

A dry cell battery works through chemical reactions (electrolyte and electrodes). These reactions generate an electric current. So, it transforms chemical energy (from the chemicals) into electrical energy (the current). Kinetic energy (movement - related) isn't relevant here. Potential energy (stored due to position) is not the main form converted. And it's not electrical to mechanical (like a motor).

Answer:

B. chemical energy into electrical energy
