It is an intrinsic property of the species. The SI unit of molar absorption coefficient is the square metre per mole ( m 2 /mol ), but in practice, quantities are usually expressed in terms of M −1 ⋅cm −1 or L⋅mol −1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol ).
In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. [1]
A state is a complete description of the observable properties of a physical system. Sometimes the word is used as a synonym of "wave function" or "pure state". State vector synonymous to "wave function". Statistical ensemble A large number of copies of a system. System A sufficiently isolated part in the universe for investigation.
Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 ·kg −1). Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance.
Good questions. The answer is that "extensive quantity" has been incorrectly defined in this article, and some of the examples are incorrect. Atkins and de Paula ("Atkins' Physical Chemistry", 8th ed 2006, W.H.Freeman, p.31) define an extensive property as a property that depends on the amount of substance (NOT the size) in the sample.
Bulk density is not the same as the particle density, which is an intrinsic property of the solid and does not include the volume for voids between particles (see: density of non-compact materials). Bulk density is an extrinsic property of a material; it can change depending on how the material is handled. For example, a powder poured into a ...
Suppose a composite property is a function of a set of intensive properties {} and a set of extensive properties {}, which can be shown as ({}, {}). If the size of the system is changed by some scaling factor, λ {\displaystyle \lambda } , only the extensive properties will change, since intensive properties are independent of the size of the ...
Extrinsic means that the chirality is a consequence of the arrangement of different components, rather than an intrinsic property of the components themself. For example, the propagation direction of a beam of light through an achiral crystal (or metamaterial) can form an experimental arrangement that is different from its mirror image.
