* Physical Change: A physical change alters the form or appearance of a substance, but not its chemical composition. Ductility refers to the ability of a material to be drawn into a wire, essentially changing its shape. The chemical makeup of the material remains the same.

* Chemical Change: A chemical change results in the formation of new substances with different chemical compositions. Ductility doesn't involve the creation of new substances, only a change in the material's shape.

Example: When you stretch a copper wire, you are changing its physical shape. The copper atoms themselves are not changing their arrangement or bonding within the material.
