Iron does not burn on heating,but iron filings burn vigorously when sprinkled in the flame of a burner.
(TRUE) The statement is True.
Explanation: When a solid piece of iron is heated,it does not burn because the surface area exposed to oxygen is small. However,when iron is in the form of fine filings,the surface area exposed to oxygen is significantly increased. This allows for a rapid reaction with oxygen in the flame,causing the iron filings to burn vigorously.
