Question
What happens to the energy stores in water when it is heated to boiling in an electric kettle?
Answer
When water is heated in an electric kettle, the thermal energy store of the water increases as electrical energy is converted into thermal energy. This causes the temperature of the water to rise until it reaches its boiling point.
Explanation
This question tests the understanding of energy transfer and changes in energy stores. The answer clearly describes the conversion of electrical energy to thermal energy and the resulting increase in the thermal energy store of the water.
Common mistake
Misunderstanding Energy Transfer
Students often think that the energy from the kettle is only stored as thermal energy in the water and forget that energy is also transferred to the kettle itself.
Remember that energy is transferred to both the water and the kettle, and describe how the energy-store changes in both components.
