Since the chemical structure of the iron (Fe) does not change, it is a physical change. I would like to point out that this does make the likelihood that a chemical change will take place higher, more energy equals a faster phase transformation. If the iron it is sitting in air, the outer surface is likely under going a chemical change into iron oxide (FeO, Fe3O4, and Fe2O3) more commonly known as rust. Hence, iron as with most metals is found as Iron oxide and processed into Iron. More facts about iron can be found here: http://en.wikipedia.org/wiki/Iron

Is heating a mixture of iron and sulfur physical or chemical change?
Heating a mixture of iron and sulfur results in a chemical change. When heated, the iron and sulfur react to form iron sulfide, a new compound with different properties than the individual elements. This transformation involves the breaking and forming of chemical bonds, indicating that a chemical reaction has occurred. Thus, the process is not merely a physical change but a chemical one.
Why Iron expands on heating is a physical change?
Iron expands on heating due to an increase in the kinetic energy of its atoms, causing them to vibrate more and occupy a larger volume. This process does not alter the chemical composition of iron; it remains iron throughout the expansion. Since the change is reversible and does not produce a new substance, it is classified as a physical change.
Is iron turned into rust a physical or chemical change?

Is heating an iron nail a physical or chemical change?
Heating is a physical change.
Is the heating of iron III oxide for sometime a physical or chemical change?
Just heating the metal would be a physical change, as you would only have a warmer iron III oxide. However, if the heat caused a reaction, it would then be a chemical change.

Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is melting iron physical change or physical property or chemical change or chemical property?
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.

Is iron rusting a physical change or a chemical change?
it is a chemical change
