Why iron filings burn vigorously when sprinkled in the flame of the burner? I need apropiate answer please if u do know then don't answer it! |

Answer» tion:For burning to occur, the surface in contact with the AIR must be heated to its ignition TEMPERATURE. ... An iron rod will not burn as it has RELATIVELY very less surface area per UNIT mass but iron filings with more surface area per unit mass can burn in air and GET converted to iron oxide. |
