Sameer notices that when a paper wheel is held over a lighted candle as shown in the diagram below, it starts to turn quickly after some time.
Q. Which of the following can be the correct reason?
- a)The heat from the candle flame heats up the surrounding air. The hot air rises and the kinetic energy of the moving air causes the wheel to turn
- b)The heat from the candle flame heats up the surrounding air. The hot air rises and the potential energy of the moving air causes the wheel to turn
- c)A and B both
- d)None of the above
Correct answer is option 'A'. Can you explain this answer?

Potential energy means it's in rest and kinetic means moving. So, here we can understand that the hot air rises up. As the air rises up which shows movement, the correct answer is option A). Rest of the options are incorrect due to the correctness of option A).

When the paper wheel is placed over a lighted candle, the heat from the flame heats up the surrounding air. As the air becomes hot, it becomes less dense and rises. The rising hot air causes a movement of air currents, and this moving air (which has kinetic energy) exerts force on the paper wheel, causing it to rotate. This is a classic example of how the movement of air due to differences in temperature (convection) can cause motion.
Option B (The hot air rises and the potential energy of the moving air causes the wheel to turn) is incorrect because it refers to "potential energy" in this context. Potential energy typically refers to energy due to position, not motion. In this case, it is the kinetic energy of the moving air that causes the wheel to turn.
Therefore, the correct reason is Option A, as it accurately describes the process involving the heat-induced movement of air and the resulting kinetic energy that makes the wheel spin.
