It is a chemical change. Here oxidation of Iron occurs and being oxidation reaction, it is 'exothermic' reaction.Through it takes prolonged period and it is difficult to observe it, you can deduct it. As 'all' oxidation reactions are 'exothermic'.

∙ 10y agoRusting is a chemical change, as steel/iron turns into iron oxide.
A chemical change is a change in it's identity (chemical formula) and sometimes its state.
A physical change is just one in its state.
So, rust would be a chemical change since there is not a way to change its identity back - only through another chemical-based method.
Freezing water, boiling water, melting metal: those are physical changes.

Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Is a rusting bicycle a physical or chemical change?
It's not the rusty bike it's the rusting of the bike. rust forms in a process called oxidation, or when iron comes in contact with oxygen. Also one reason you can tell it's a chemical change is when you can't reverse the process. Or when it involves changing the chemical compound.

Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
