Magnetizing a paper clip is considered a physical change. This is because the process of magnetization does not alter the chemical composition of the paper clip. The magnetic properties are induced by aligning the magnetic domains within the material, which is a reversible process. Chemical changes, on the other hand, involve the formation of new substances with different chemical properties.

Is magnetizing iron a physical change?
Yes, magnetizing iron is a physical change because it does not alter the chemical composition of the iron. When iron is magnetized, its magnetic domains align to create a magnetic field, but the iron itself remains unchanged chemically.
Is magnetization of an iron nail a chemical change?
physical change
Is extraction a physical or chemical change?
Extraction is considered a physical change because it involves separating substances based on their physical properties, such as solubility or boiling point, without changing the chemical composition of the substances being separated.
Is pop fizzing a physical change?
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.

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 evaporation considered a chemical or physical change?
Evaporation is considered to be a physical change. The chemical nature and identity of the evaporated material is the SAME as that of the liquid.

Is dissolving salt chemical change?
Dissolution is considered a physical change.
