The point E (The transition point): At this point , the anhydrous sodium sulphate exist in rhombic, monoclinic and solution form. So applying the reduced phase rule. F = C P+ 1 =2-3+1 =0 Thus point E is also invariant point The phase Rule is an important generalization dealing with the behaviour of heterogeneous systems. In general it may be said that with the application of phase rule it is possible to predict qualitatively by means of a diagram the effect of changing pressure, temperature and concentration on a heterogeneous system in equilibrium

Phase rule: • Phase is a homogeneous, physically distinct portion of a system that is separated from other portions of the system by bounding surfaces • Phases coexistence can only occur over a limited range.

It then discusses phase diagrams for some representative types of multicomponent systems, and shows how they are related to the phase rule and to equilibrium concepts developed in Chaps. 11 and 12. 13.1 THE GIBBS PHASE RULE FOR MULTICOMPONENT SYSTEMS In Sec. 8.1.7, the Gibbs phase rule for a pure substance was written F D 3 P.Weno F= K+ 2 P (Gibbs phase rule): The maximum number of coexisting phases is K+ 2, which is realized for F = 0. In this case, no intensive variables need to be speci ed. All are determined by the conditions of phase coexistence. Example: 1-component uid (K= 1) P= 1 (one phase): F= 2 means that both pand Tmust be speci e

Gibbs Phase Rule is expressed by the simple formulation: P + F = C + 2, where. P is the number of phases in the system. A phase is any physically separable material in the system. Every unique mineral is a phase (including polymorphs); igneous melts, liquids (aqueous solutions), and vapor are also considered unique phases 2. In two phase region draw the tie line or isotherm . 3. Fraction of a phase is determined by taking the length of the tie line to the phase boundary for the other phase, and dividing by the total length of tie line .

A condensed phase rule is the one used to represent the phase diagram of a condensed system, either liquid or solid. In such a case, for two or more components, the phase diagram becomes multidimensional. Look at, F = C - P + 2, for one phase, 2 - 1 + 2 = 3 and the phase diagram will have three dimensions CORE RULES Warhammer 40,000 puts you in command of an army of mighty warriors and war machines as you battle for supremacy in the grim darkness of the far future.
