Energy Forms and Transformations

Which of the following best describes the energy transformations that occur when a flashlight that runs on batteries is turned on?

• chemical → light → electrical
• electrical → light → chemical
• light → electrical → chemical
• chemical → electrical → light

The Theory of the Conservation of Energy states -

• Energy can be created, just not destroyed. It changes its form from one type to another.
• Energy can never be created nor destroyed. It can only change its form from one type to another.
• The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.
• Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.
