Yes, because corrosion takes place in the process.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Yes, the rusting of a bicycle is a chemical change because it involves the oxidation of the iron in the metal to form iron oxide (rust), which is a different chemical compound than the original metal. This process is irreversible.
No apparently it is physical change. All elements used are still visible such as wood, cement etc though it's been broken down to smaller pieces changing it's form to create another structure their chemical nature has not been altered.
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.

Ah, what a lovely question. When a bicycle rusts, it's actually a chemical change taking place. The metal is reacting with oxygen and moisture in the air, creating a new substance called iron oxide. It's all part of nature's way of transforming things, just like how we transform a blank canvas into a beautiful painting.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
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.
