Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
No, bending a paper clip is a physical change because the material of the paper clip remains the same before and after bending. Chemical changes involve a change in the chemical composition of a substance.
Rusting of a paper clip is a chemical change. It involves the iron in the paper clip reacting with oxygen in the air to form iron oxide (rust). This change is not reversible and results in a new substance with different properties.
Yes, burning a paper clip is a chemical change because it involves a chemical reaction where the paper clip combines with oxygen to produce new substances like ash and possibly some metal oxides.
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.

No, bending a paper clip is a physical change because the material of the paper clip remains the same before and after bending. Chemical changes involve a change in the chemical composition of a substance.
No, picking up a paper clip with a magnet is not a physical change. It is a demonstration of magnetic force and involves no permanent alteration to the paper clip's structure or composition.
Bending a paper clip is a physical change because the composition and structure of the paper clip remain the same. No new substances are formed during this process.

Picking up a paper clip with a magnet is a physical change because no new substances are being created. The paper clip's position is simply being altered by the magnetic force.
