Something that transforms chemical energy to light
and sound energy

When a match is struck, it emits light, sound, and thermal energy. All this energy had been stored in the match in the form of chemical energy. Chemical energy is the potential energy stored in the bonds between the atoms of a substance. The sources of this stored energy are the electromagnetic force fields of the charged particles that make up the atoms. Interactions among these fields provide energy that can be released during a chemical reaction.

the dissolution of polymer can be thermodynamically described in 2 steps.
