Physical change: bending.
Chemical change: Rusting (oxidation).
An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
A physical change in iron is anything that causes it to change shape, such as striking it with sufficient force to cause it to bend or dent.
A chemical change in iron is anything that causes a change in its molecular structure. An easy example of this is the process of forging iron into steel, which involves forcing carbon and sometimes other elements into the molecular bonds of the iron.
An example of both is oxidation, or rust. Initially rust is a chemical change, but as the chemical changes develop to affect a larger and larger portion of the iron, it will cause pieces of the iron to expand and eventually flake off, changing the appearance and surface shape of the iron.

When it combines with Oxygen. Commonly called Rust.
No. Iron is naturally magnetic.
Iron is a chemical element, not a "change" !
Iron is a chemical element, not a "change".
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
Physical change
The process of iron rusting is a chemical change.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
rust is a chemical change for iron
It is a chemical change.
It is a physical process. Not really a change of any kind.
