Description of matter on the led to predicted macroscopic properties and their reactions to external stresses The scratch of a material is a prime consideration in choosing materials for construction of mechanical tools or machines where friction is an issue. Matter can undergo two kinds of change: not in composition; is a change in composition. Extensive properties, such as mass, depend on sample ; intensive properties, such as temperature, do not.
A matter can be described on two different scales. That is, the mater that is described based on smallest scale in terms of atoms and molecules and its properties, this is microscopic scale. On the other hand, when the matter is described based on the collective properties of these individual atoms and molecules, which constitute the overall properties of the matter then it is a macroscopic scale.
In example, the overall properties of a polymer that is synthesized depends on the microscopic properties of the molecules and the monomer that constitute the polymer. Some of the microscopic properties of a matter intermolecular forces, ionization energy, electronegativity, electron affinity, etc. Some of the macroscopic properties include physical and chemical properties such as melting point, freezing point, boiling point, reactivity, reduction potential.
