Solid phase lowest free energy

WebUsing the phase diagram above, answer the following questions. 1. Which phase has the lowest free energy at 0.50 atm and 100 K? The Solid phase. We can see this on the phase diagram because the point with the P=0.50 atm and T=100 K falls in the Solid phase region. 2. Which phase has the lowest free energy at 1.75 atm and 350 K? The Liquid phase. WebAug 3, 2024 · The free energy involved in the formation of an interface between two phases (e.g., a solid–liquid interface) is referred to as the interfacial free energy.
