no it is a chemical 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.
Rust, scientifically known as oxidation, is a chemical change.
Yes, rusted pots and pans are a result of a chemical change. This occurs when the metal reacts with oxygen and water to form iron oxide (rust), which is a different substance than the original metal.
Rust is not very strong.
Melting is a physical change of iron.
Melting an iron rod is a physical change
Rusted cast iron.
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.
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Rusted iron is generally weaker than non-rusted iron, as the rust (iron oxide) can create a brittle layer that compromises its structural integrity. This degradation makes rusted iron more susceptible to breaking or crumbling under stress. While some areas may still retain strength, overall, rusted iron is considered less durable and more easily broken compared to its non-rusted counterpart.
Iron is a chemical element, not a "change".
