- If something converts one kind of energy into other kinds of energy then that something originally stores that energy as the first kind of energy
- A firecracker converts chemical energy into sound energy and light energy and heat energy
- Therefore, the firecracker stores chemical energy as its original energy

Therefore, the firecracker stores chemical energy as its original energy
Question: The sound, light, and heat that a firecracker produces are originally stored as which type of energy?
Context: - If something converts one kind of energy into other kinds of energy then that something originally stores that energy as the first kind of energy 
- A firecracker converts chemical energy into sound energy and light energy and heat energy
