| ductility | the ability to be stretched into wire |
| flammability | the ability of a substance to burn |
| freezing point | the temperature at which a substance freezes |
| inertia | the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object |
| Law of Conservation of Mass (Matter) | the law that states that mass cannot be created or destroyed in ordinary chemical and physical changes |
| malleability | the ability to be hammered or shaped without breaking |
| mass | a measure of the amount of matter in an object |
