No. Any change of state (solid to liquid, liquid to gas, etc.) is a physical change.
When the steel wool burns, it is oxidized and thus this is a chemical change.
Sure. A steel frame that begins to rust will be undergoing a chemical change.
Physical
Chemical. Rusting is known as "oxidization," a chemical reaction where oxygen reacts with iron.
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.
Rusting is a chemical change, as steel/iron turns into iron oxide.
no rusting iron is not a physical change it is a chemical change
The simple act of melting the steel is a physical change. No one melts steel out of boredom. If the melt is so you can add other elements to it, then you've made a chemical change. If you're forming useful products from the steel without changing its chemistry, it's a physical change.
physical, just the aligning of magnetic domains what were previously random in orientation.

By heating steel and melting it, steel can be changed into a liquid.
No it is just putting it into a different form. for example if you had some jello, and then you cut it up to make a cube that wouldn't be a chemical change either. see?
