Question
- A. 10000 J
- B. 1000 J
- C. 2000 J
- D. 5000 J
Answer
10000 J
Explanation
The correct option is "10000 J". 10000 J is right because it directly matches Energy stores and systems: Calculate changes in energy when a system is changed by heating.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Common Mistake in Energy Calculation
Students often forget to convert units when calculating changes in energy, leading to incorrect answers.
Always check that mass is in kilograms and energy is in joules before performing calculations.
