Transfer of Energy Level 3

The Law of Conservation of Energy states;

• Energy can be created and destroyed but can be transferred and transformed.
• Energy can be created but not destroyed and cannot change.
• Energy can be made at any time.
• Energy can not be created or destroyed but can be transferred and transformed.
