Question

how physical energy differ from chemical energy

Answer 1

Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances. Examples include batteries, food, gasoline, and etc.. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system. A very common misconception is that energy is released when bonds are broken, whereas energy is required to break bonds.
