Electrical → Mechanical → Sound
Which device were the students most likely observing?A triple beam balance measuring an object’s mass.A pencil sharpener plugged into a wall outlet.A projector displaying a diagram on the screen.A working flashlight used to light up a dark corner. - 2. Multiple ChoiceWhich of these is an example of light energy being transformed into chemical energy?A glow stick lights up when broken.Water heated by the sun evaporates.A plant makes sugar in the sunlight.A battery causes a buzzer to vibrate.
- 3. Multiple ChoiceWhich kind of energy change occurs when a candle is burning?Chemical to light.Light to electrical.Solar to heat.Chemical to electrical.
- 4. Multiple ChoiceWhich type of energy transformation occurs when a flashlight shines?chemical → thermal → electricalchemical → electrical → lightthermal → chemical → lightchemical → electrical → chemical
- 5. Multiple ChoiceWhen 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 → mechanicalchemical → mechanical → electricalmechanical → chemical → lightmechanical → electrical → light
- 6. Multiple ChoiceA lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformations are taking place?chemical → light → electricalmechanical → sound → lightthermal → solar → electricalelectrical → thermal → light
- 7. Multiple ChoiceWhich of the following best describes the energy transformations that occur when a flashlight that runs on batteries is turned on?chemical → light → electricalelectrical → light → chemicallight → electrical → chemicalchemical → electrical → light
- 8. Multiple ChoiceWhich of the following shows the correct order of the energy transformations that occur when green plants produce their food from the Sun’s energy?chemical → thermallight → chemicalthermal → lightchemical → electrical
- 9. Multiple ChoiceWhich of the following shows the energy transformation that occurs when solar panels are used to heat a building?light → thermalchemical → electricalthermal → chemicallight → mechanical
- 10. Multiple Choice
The picture shows a light bulb attached to a hand generator. What energy transformation occurs as the handle of the generator is turned?thermal → solar → lightsolar → light → electricalmechanical → electrical → lightelectrical → mechanical → light - 11. Multiple ChoiceWhich device transforms electrical energy into mechanical energy?FlashlightPencil SharpenerLampTV
- 12. Multiple ChoiceThe picture shows a microwave oven. As a microwave oven is operated, electrical energy is transformed into all of the following types of energy EXCEPT —SolarLightThermalMechanical
- 13. Multiple ChoiceThe diagram shows a circuit with the bulb glowing. How does the energy change as it moves from inside the battery, along the wires, and through the light bulb?electrical → light → chemicallight → electrical → chemicalchemical → electrical → lightchemical → light → electrical
- 14. Multiple ChoiceWhich of the following systems transforms chemical energy to light energy?FanLampCompassBurning a candle
- 15. Multiple ChoiceThe 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.
