Is a sugar cube grounded up a chemical or physical change?
Physical.
Hammering hot iron into a sheet chemical or physical change?
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
When iron rust is it a physical change?
No. Rusting is a chemical change.
Is heating of iron wire physical or chemical change?
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
What is a example of a physical change of iron?
Melting is a physical change of iron.
Is melting a iron rod a physical change?
Melting an iron rod is a physical 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 melting a physical change?
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
Is bending an iron nail physical change or chemical change?
physical
Is heating an iron nail a physical or chemical change?
Heating is a physical change.
Why is a rusted nail chemical change not physical change?
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
Is rusted iron physical change?
no it is a chemical change

Is rusting of an iron fence a physical change?
No, it is a chemical change (conversion to iron oxide)
