Energy transformations

Which type of energy transformation occurs when a flashlight shines?

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

When water falls through a dam and turns a turbine connected to a generator, electricity is produced. This electricity is often used to light our homes and offices. Which of the following shows the energy transformations that occurs?

• electrical → light → mechanical
• chemical → mechanical → electrical
• mechanical → chemical → light
• mechanical → 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.
