Expert Answer
Dear student
A big iron bar doesnot burns while iron fillings burn vigorously because iron bar has very large surface area in comparison to iron fillings thus a very large amount of heat enegy is required to burn it while iron fellings having very small surface are doesa not need high amount of heat and thus they burn easily.
We hopr that clarifies your doubt
