Rusting is the oxidation of iron. To prevent rusting you must prevent oxygen from coming into contact with the product. This is normally acheived by applying a barrier of oil in working environments. Products are available for storing materials for long periods to avoid rusting. These have a more waxy nature than oil and would not be suitable to use to stop rusting in a mechaincal item. Of course if you want to prevent rusting and for it to look nice. various paints and lackers can be applied. Chemical coatings can also be applied to prevent rusting. Or simply keep the item clean and dry and rusting can be slowed.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
no rusting iron is not a physical change it is a chemical change
Yes, it is.
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.
Painting of iron prevent it from rusting because it prevent the iron articles coming in Contact with oxygen, or water vapours present in the air.

Steel castings can prevent rusting depending on what the kind of steel. Carbon steel may cause rusting at a higher rate than stainless steel.
give 2 ways of preventing damage to diskettes
Some ways to prevent rusting include using rust-resistant materials like stainless steel, applying protective coatings like paint or zinc plating, keeping metal surfaces dry and well-ventilated, and using rust inhibitors or desiccants to absorb moisture. Regular maintenance and cleaning can also help prevent rust from forming.

Aluminum does not rust like iron does. Instead, it forms a thin layer of aluminum oxide on its surface which protects it from further corrosion. This layer acts as a barrier, preventing the metal from rusting.
five ways for green computing
The most effective rusting solution for preventing corrosion on metal surfaces is applying a protective coating such as paint, oil, or a specialized rust inhibitor. These coatings create a barrier between the metal and the environment, preventing moisture and oxygen from reaching the metal surface and causing rust. Regular maintenance and inspection of the coating are also important to ensure continued protection against corrosion.

Keeping an outdoor table dry and covered from the elements will help keep it from rusting. Paste wax, greasing, and rust-proof paint are other ways to keep them from rusting if you're unable to keep them out of the rain.
Paint can protect iron from rusting, especially if it is the right kind of paint - you would not want to use a water based acrylic paint, since the water in the paint would promote rusting, rather than preventing it.
