Question

multiple - choice question
what kind of energy does firewood, batteries, and food have?
gravitational potential energy
elastic potential energy
kinetic energy
chemical potential energy
rewatch

Explanation:

Firewood, batteries, and food contain stored - chemical energy. Chemical potential energy is energy stored in the chemical bonds of substances. When these substances react (such as firewood burning, a battery discharging, or food being metabolized), the chemical potential energy is released. Gravitational potential energy depends on an object's height and mass, elastic potential energy on an object's elasticity and deformation, and kinetic energy on an object's motion. Since firewood, batteries, and food are stationary and store energy in their chemical structure, they have chemical potential energy.

Answer:

Chemical Potential Energy
