Magnetization of iron is considered a physical change because it involves the alignment of magnetic domains within the material without altering its chemical composition. When iron is magnetized, its physical properties, such as its magnetic field, change, but the structure and identity of the iron remain intact. This means that the process is reversible; demagnetizing the iron will restore it to its original state.

Why magnetisation and demagnatisation are physical change?
Magnetisation and demagnetisation are considered physical changes because they involve a change in the arrangement of magnetic domains within a material without altering its chemical composition. When a material is magnetised, its magnetic domains align in a particular direction, while demagnetisation causes them to return to a random orientation. These processes do not involve any chemical reactions or formation of new substances, reinforcing their classification as physical changes.
Hammering hot iron into a sheet chemical or physical change?
Hammering hot iron into a sheet is a physical change. The process involves changing the shape and size of the iron without altering its chemical composition. The atoms in the iron remain the same, only the physical properties are altered.
Is a sugar cube grounded up a chemical or physical change?
Physical.
Is iron nail rusts in water a chemical change or a physical change?

Is melting iron physical change or physical property or chemical change or chemical property?
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
Is iron melting a physical change?
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
Is iron physical changes or chemical changes?
Iron is NOT a chemical nor physical change. Iron is a solid metallic element.
Is bending an iron nail physical change or chemical change?
physical
Is making iron from iron ore a chemical or physical change?
Preparation of pure iron from iron ores involve physical changes but also chemical changes.
Is heating an iron nail a physical or chemical change?
Heating is a physical change.
Why is a rusted nail chemical change not physical change?
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
