The blending of steel (making alloys) is a physical process. Though the structure of the steel changes, it is still chemically unaltered.
Blending steel is a physical property because it involves mixing two or more steel components without changing the chemical composition of the material. The process does not create new substances but instead alters the physical state of the steel.
The fact that chromium is a steel gray solid is a physical property because it relates to its appearance and state of matter. Chemical properties, on the other hand, involve the way a substance interacts with other substances to form new substances.
When the steel wool burns, it is oxidized and thus this is a chemical change.
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
Resistance to corrosion is a chemical property because it is a characteristic that describes how a material interacts with its environment on a molecular level. It is determined by the material's chemical composition and its ability to react with substances in its surroundings.
no, its physical change :)

chemical property
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Magnetizing a piece of steel, a needle for example, is a physical change, for it causes the spin of a group of electrons to be co-alignedrather then randomly oriented. The chemical composition of the steel is unchanged.
Chemical- changed it into something new!
physical, just the aligning of magnetic domains what were previously random in orientation.
Rusting of steel wool is a chemical change because it involves a reaction between iron in the steel wool and oxygen in the air to form iron oxide (rust). This new substance has different properties than the original steel wool.
Rusting is a chemical change, as steel/iron turns into iron oxide.
