Verified step by step guidance1
Begin by understanding the different types of energy mentioned in the problem: chemical energy, kinetic energy, thermal energy, and potential energy.
Chemical energy is the energy stored in the bonds of chemical compounds, like molecules in food. When these bonds are broken during digestion, energy is released.
Kinetic energy is the energy of motion. It is not stored in food, but rather is associated with moving objects.
Thermal energy is related to the temperature of a system and is the energy that comes from the movement of atoms and molecules in a substance.
Potential energy is the energy stored due to an object's position or arrangement. In the context of food, chemical energy is a form of potential energy because it is stored in chemical bonds.
