Explain how energy is conserved in a closed system.

• Energy is conserved because it can only change forms outside the system.

• Energy is conserved because it can be created and destroyed at will within the system.

• Energy is conserved because it can neither be created nor destroyed, only change forms within the system.

• Energy is not conserved in a closed system.
