Develop a model to show the chemical potential energy of wood and how that energy is transformed.
Phantasy [73]

Answer:

Explanation:

Chemical potential energy is the chemical energy stored (or property) of a substance. One chemical potential energy of wood is combustion. Combustion involves the burning of a substance in excess oxygen (in this case open air). <u>The chemical energy stored here is transformed to thermal/heat energy after combustion due to the large amount of heat evolved/produced</u>.

NOTE:

The model above also that combustion is an exothermic reaction because it involves the release of heat into it's surrounding.
