200
Useful energy is organized energy. As energy transformation occurs, some organized energy is converted into disorganized energy. This means that the total amount of disorganized energy in the universe is always_____
What is increasing.
200
Energy that is stored in the nucleus of an atom and is released when changes occur in the nuclei of atoms is ____________ ____________.
What is nuclear energy.
300
