Question
Wrap a thin paper strip tightly around an iron rod. Try to burn the paper with candle while rotating the iron rod continuously. Does it burn? Explain your observation.
Solution
- When you wrap a thin paper strip tightly around an iron rod and try to burn it with a candle while rotating the rod continuously, the paper does not burn.
- This is because the iron rod absorbs and conducts away the heat from the candle flame, preventing the paper from reaching its ignition temperature.
- The continuous rotation ensures that no single part of the paper is exposed to the flame long enough to catch fire.
