A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Properties may also be classified with respect to the directionality of their nature. For example, isotropic properties do not change with the direction of observation, and anisotropic properties do have spatial variance. It may be difficult to determine whether a given property is a material property or not.
A composite or composite material (also composition material) is a material which is produced from two or more constituent materials. [1] These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements.
Materials physics is the use of physics to describe the physical properties of materials. It is a synthesis of physical sciences such as chemistry , solid mechanics , solid state physics , and materials science.
The physical properties [31] of polymer strongly depend on the length (or equivalently, the molecular weight) of the polymer chain. [32] One important example of the physical consequences of the molecular weight is the scaling of the viscosity (resistance to flow) in the melt. [33]
A material is a substance or mixture of substances that constitutes an object.Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function.
An extensive property is a physical quantity whose value is proportional to the size of the system it describes, [8] or to the quantity of matter in the system. For example, the mass of a sample is an extensive quantity; it depends on the amount of substance. The related intensive quantity is the density which is independent of the amount.
Some of the relationships that physical chemistry strives to understand include the effects of: Intermolecular forces that act upon the physical properties of materials (plasticity, tensile strength, surface tension in liquids). Reaction kinetics on the rate of a reaction. The identity of ions and the electrical conductivity of materials.
