Step 1 of 3
FundamentalEquations,MaxwellRelation, andMaterialEquilibrium st nd By combining 1 law and 2 law of thermodynamic one would get: + − < 0 This is the condition for spontaneous change in terms of U, P, V, T, S By putting conditions and constraints to create criteria for equilibrium: 1. Isolated system: = = 0 ∆ = 0 ∆ = 0 Plugging this into the combination equation: − < 0 ,
