If V is constant, this means a variation in number density n = N=V. WebIn other words, the total potential energy is extensive for short-range interactions (α / d > 1), and nonextensive for long-range interactions (0 ≤ α / d ≤ 1). Satisfactorily enough, Equation recovers the characterization with ∫ 1 ∞ d r r d r − α in the limit N → ∞, but it has the great advantage of providing, for finite N, a ...

The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object's mass and volume, which are two extensive properties, is density, which is an intensive property. More generally properties can be combined to give new properties, which may be called derived or composite properties.

WebApr 6, 2024 · Gibbs free energy is defined by other state functions (G=H-TS), enthalpy, and entropy. Additionally, Gibbs free energy is a state property because it is defined by final-initial state and is not dependent on the path it undergoes during the change. Gibbs free energy is also an extensive property. WebGibbs energy is an extensive property i.e it is independent of the amount of substance present. And it can be directly added or subtracted. The spontaneous nature of a cell reaction is dependent on Gibbs energy. Case 1:- If Ecell is positive (+ve). As the change in Gibbs energy is negative, the cell reaction is spontaneous.
