Question

the energy in coal is used to make electricity. how is the energy stored in coal?

a. in chemical bonds

b. as light energy

c. in the nucleus

d. as kinetic energy

Explanation:

Coal is a fossil fuel formed from organic matter. The energy in coal is stored in the chemical bonds of its molecules (like carbon - hydrogen, carbon - carbon bonds). Light energy is not how energy is stored in coal (coal doesn't store energy as light). Energy in the nucleus is related to nuclear energy (e.g., in radioactive materials or nuclear reactions), not coal. Kinetic energy is the energy of motion, and coal is a solid at rest, so it doesn't store energy as kinetic energy. So the correct option is A.

Answer:

A. In chemical bonds
