Yes, because corrosion takes place in the process.
Isn't it a chemical change? Since corrosion is usually the reaction of metals with water and oxygen.

A chemical change to a bike fram would be if the frame rusts.
Corrosion is a chemical change.
Yes. Iron turning into iron oxide(rust) is a chemical change.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Burning is a chemical change.

It's a chemical change
Sure. A steel frame that begins to rust will be undergoing a chemical change.
That'd be a chemical change, as steel/iron turns into iron oxide. Usually called rusting, or corroding.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
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.

first physical, second chemical
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
