Which best describes energy changes in a system? A) energy is conserved, but it can be created or destrayed B) energy is conserved, and it cannot be created or destroyed C) energy is not conserved, and it can be created or destroyed D) energy is not conserved, but it cannot be created or destroyed

Answer 1

The best description of energy changes in a system is:

B) energy is conserved, and it cannot be created or destroyed.

This principle is known as the law of conservation of energy, which states that the total energy in an isolated system remains constant over time. Energy can change forms (e.g., from kinetic to potential energy), but the total amount of energy does not change.
