Answer:
Concept:
A chemical element mixture called an alloy must contain at least one metal. The properties of a metal, such as electrical conductivity, ductility, opacity, and lustre, will all be retained in the alloy's final product, unlike chemical compounds with metallic bases, but an alloy may also have additional properties that aren't present in pure metals, such as increased strength or hardness. In some circumstances, an alloy may keep vital qualities while lowering the material's overall cost. In other instances, the mixture endows the constituent metal elements with synergistic qualities like corrosion resistance or mechanical strength.
Given:
The temperature of all these phases will be for a binary alloy with three non-equilibrium phases.
A. Constant
B. Two of them will be with one temperature
C. Different
D. Same
Answer:
The correct answer is option (D) same
By examining for non-equilibrium conditions using the aforesaid method, we learn one application for the Gibbs phase rule.
The Gibbs' Phase Rule, based on thermodynamics, provides the theoretical framework for describing the chemical state of a (geologic) system and predicting the equilibrium connections of the phases (minerals, melts, liquids, and vapours) present as a feature of physical conditions like pressure and temperature.
In order to describe and understand phase equilibrium in heterogeneous geologic systems, Gibbs' Phase Rule also enables us to create phase diagrams. The borders of stable phase assemblages are established by lines (or curves) that depict reactions between the phases assemblages in the most basic interpretation of phase diagrams. Stable phase (mineral) assemblage are represented as "fields" (see coloured areas on the picture to the right). The locus of locations in P-T space where Grxn = 0 is really represented by the reaction curves; for more information on this concept, see Gibbs Free Energy. To successfully comprehend the applications of heterogeneity phase equilibria given in this section, a firm grasp of Gibbs' Phase Rule is necessary.
