Which energy form is energy stored in chemical bonds?

• A. Potential energy
• B. Chemical potential energy
• C. Gravitational potential energy
• D. Mechanical energy

Answer: (B)

Energy stored in chemical bonds is chemical potential energy. This energy comes from the way atoms are arranged and the bonds that hold them together; when bonds break and new bonds form during a chemical reaction, energy is released or absorbed. Because this energy depends on the chemical structure rather than motion, it’s a type of potential energy rather than kinetic energy. Gravitational potential energy depends on height in a gravitational field, and mechanical energy describes the total energy of motion and position, not specifically the energy stored in bonds. Things like gasoline, food, and batteries store energy in chemical bonds, which can be released to do work when those bonds are altered.
