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
Mixing elemental iron and elemental sulfur is actually physical, but the mixture stays heterogenous. The particles of iron do not interchange with those of the sulfur.
If they were to be melted and alloyed then it would be a physical change, but this is not reality:
In stead they react (chemically!) when heated to form ferrous sulfide, FeS, which is a totally new compound.
Fe + S --> FeSdepends...this is physical science so if you mely them together it would be a chemical change but seperatly itd be a physical change

Is a sugar cube grounded up a chemical or physical change?
Physical.
Is iron turned into rust a physical or chemical change?
Chemical change.
What type of physical change is heating iron to get liquid iron?
Melting, that's it
Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
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 heating iron nail chemical or physical?

Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is steel wool physical or chemical change?
Steel wool rusting is a chemical change because it involves a reaction with oxygen to form iron oxide. This results in a change in the chemical composition of the steel wool.
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.
