Bending of Metal is aPhysical Change but Corossion of Metal is a Chemical Change. Chemical Properties: It is the internal properties of a substance. For example, we can get curd from milk because it is the product of milk but for each of them, internal properties are completely different.

Is bending a wire a physical or chemical change?
Bending a metal wire changes the shape of the wire, which is a physical property, but does not change the molecular formation of the wire/ the stuff that makes up the wire. The wire is still a wire. What are some ways to tell if a change is physical?
What happens to a material when it undergoes a physical change?
A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced. A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
Is melting a physical or chemical change?
A physical change involves changes in physical properties, but not chemical properties. For example, physical properties change during tempering steel, crystallization, and melting. Here are examples of physical changes: Crumpling a sheet of aluminum foil. Melting an ice cube.
What are some examples of chemical and physical changes?
Here are some examples of chemical changes: No new chemical species forms in a physical change. Changing the state of a pure substance between solid, liquid, or gas phase is a physical changes since the identity of the matter does not change. A physical change involves changes in physical properties, but not chemical properties.
