Final answer:
Malleability is a physical property that describes a substance's ability to be deformed without breaking, such as gold being stretched into thin wires.
Step-by-step explanation:
Malleability is considered a physical property of a material. It refers to the ability of a substance, such as a metal, to be deformed or bent without breaking. For example, gold, which is highly malleable, can be stretched into very thin wires without breaking. This property is observable and measurable without changing the identity or composition of the substance, which is characteristic of physical properties.
In contrast, a chemical property describes a substance's potential to undergo a chemical change, forming new substances with different properties. Flammability, for example, is a chemical property because it involves a substance like wood or gasoline reacting chemically with oxygen in the air to produce fire, which results in new substances such as carbon dioxide and water vapor.
