Video

Example of energy transfer— boiling water using an electric kettle

Video

What is this?

What will happen?

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

Electricity

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

Energy transfer occurs, from electrical to thermal

Video

What happened to the water when it starts boiling?

The water moves around inside the kettle

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

Moving things have kinetic energy

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

What can you hear when the water is boiling?

Another unwanted transfer in the kettle is to Sound energy
