The food we eat contains chemical energy. What kind of energy is contained within the molecules of a candy?

A Candy bar has chemical potential energy because the molecules store energy that our bodies use when we eat it.

Chemical Energy

Explanation:

Food energy is chemical energy that animals (including humans) derive from food through the process of cellular respiration. Cellular respiration may either involve the chemical reaction of food molecules with molecular oxygen [1] ( aerobic respiration ) or the process of reorganizing the food molecules without additional oxygen ( anaerobic respiration ).

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
