Chemical - It's the iron atoms reacting with the oxygen atoms in the air. For future reference, a chemical change is irreversible, whereas a physical change can be reversed, usually quite easily.
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
Rusting of a screw is a chemical change. It involves a chemical reaction between the iron in the screw and oxygen in the air to form iron oxide (rust).
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.

Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Rusting is a chemical change, as steel/iron turns into iron oxide.
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.
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
Metal rusting (corrosion) is a chemical change.
rusting is not a physical changeit is a chemical change
Rusting is a chemical change.
