A chemical property is a characteristic that is observed when a substance interacts with another substance. Examples of chemical properties are flammability, rusting, and souring.
A change that alters the form or appearance of a material, but does not make the material a substance is called a physical change. Examples of physical changes are chopping wood, bending copper wire, and molding clay.
