MATS 3011 Lecture Notes - Phase Rule, Low-Density Lipoprotein
Document Summary
Today: gibb"s phase rule, phase diagrams, lever rule and tie lines, morphology, eutectics. Gibb"s phase rule: answers the question: how many phases are possible @ eqbm given # species (components) and degrees of freedom (f, how many variables do we have control over (p, t, x)) F = n - + 2 where n = # species/components. @ red point, have 2 phasesliquid and vapor coexist. F = 1 - 2 + 2 = 1 --> can only control 1 variable in red point 2, f = 1 - 1 + 2 = 2. P = 1 atm (constant)slightly different diagram @ different p"s liquidous line solidous line above ex: ge-si or cu-ni. Matsci page 1 solidous line above ex: ge-si or cu-ni. = solid phase where cu and ni mix in all proportions in single-phase regions, f = 2 - 1 + 2 = 3.
