10. Example of energy transfer— boiling water using an electric kettle

11. Video

12. What is this?

13. What will happen?

14. What type of energy can the kettle get from the socket?

15. Electricity

16. The water starts boiling now, will it get warmer or cooler?

17. Energy transfer occurs, from electrical to thermal

18. Video

19. What happened to the water when it starts boiling?

20. The water moves around inside the kettle

21. How to describe the “moving” energy? Let’s go to BBC Bitesize

22. Moving things have kinetic energy

23. The water moves around inside the kettle so energy is wasted as
Kinetic
energy

24. What can you hear when the water is boiling?

25. Another unwanted transfer in the kettle is to
Sound energy
