MSE 3050, Phase Diagrams and Kinetics, Leonid Zhigilei Fundamental equations Combined statement of 1 st and 2 nd Laws of Thermodynamics: dU = TdS – PdV This equation gives us ¾ Relationship between the dependent variable U and independent variables V and S: U = U(S,V) or dU = ( U/ S) v dS + ( U/ V) s dV ¾ The criteria for equilibrium: in a system of constant V and S, the internal energy has its minimum value, or, in a system of constant U and V, the entropy has its maximum value. The problem is that the pair of independent variables (V,S) is rather inconvenient – entropy is hard to measure or control. We
