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.

संक्षेप में उत्तर

उत्तर

  • 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.
