Why is magnetizing a piece of steel a physical change?
It's because
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.
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.
Is magnetizing steel a chemical change or physical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
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.

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 :)
Is shaping of steel a chemical change?
No, shaping of steel is a physical change, not a chemical change. The steel's chemical composition remains the same before and after shaping, only its physical properties, such as shape and size, are altered.
