• A phase is a form of matter that is homogeneous in chemical composition and physical state. Typical phases are solid, liquid and gas. Two immiscible liquids (or liquid mixtures with different compositions) separated by a distinct boundary are counted as two different phases, as are two immiscible solids. • The number of components (C) is the number of chemically independent constituents of the system, i.e. the minimum number of independent species necessary to defin… peat worksWebJun 4, 2015 · The Gibbs phase rule and Duhem’s theorem assure us that the problem illustrated in Fig. 1 can be solved.
