Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. Energy is transferred from the kettle to the water, increasing its thermal energy
- B. Energy is transferred from the water to the kettle, decreasing its thermal energy
- C. Energy is lost to the surroundings, reducing the water's temperature
- D. Energy is stored in the kettle without affecting the water
Answer
Energy is transferred from the kettle to the water, increasing its thermal energy
Explanation
When water is heated in an electric kettle, energy is transferred from the kettle's heating element to the water, increasing its thermal energy and raising its temperature.
Common mistake
Misunderstanding Apparatus
Students often confuse the purpose of different apparatus used in specific heat capacity experiments, such as calorimeters and thermometers.
Review the function of each piece of equipment and how it contributes to measuring temperature changes and energy transfer in the experiment.
