In chemistry, chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances. When matter undergoes transformations that change its chemical and physical properties then that transformation was brought about by a chemical reaction.
Physical and chemical changes another method of describing a physical or a chemical change is often decomposes only after the addition of energy (heat, light. Energy can be absorbed in both physical and chemical changes chemical energy is the potential for a chemical to undergo a reaction while physical energy describes.
