Is magneting steel physical or chemical change?
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.
Is magnetizing steel a chemical change or physical change?
physical, just the aligning of magnetic domains what were previously random in orientation.

Is magnetizing steel a chemical or a physical?
physical, just the aligning of magnetic domains what were previously random in orientation.
Why is magnitizing a piece of steel a physical change?
Cause you're changing the direction of the atoms when you magnetize it.
What is a physical change of steel wool?
Melting the steel wool is a physical change.
Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is melting steel a chemical or physical change?
Melting steel is a physical change because only its physical state is altered, going from a solid to a liquid, without changing its chemical composition.
What type of change is melting steel?
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.
Is magnetism steel a physical change or chemical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
What is more dense a 5 gram piece of lead of 10- gram piece of steel?
density is a physical property of the material, it has nothing to do with the size of the piece. lead is 11.35 g/cc iron is 7.874 g/cc steel is between 7.75 and 8.05 depending upon type of steel.
Is dissolving steel into acid a chemical change?
no, its physical change :)
