Exercise : Temperature dependence of Gibbs Free Energy

Supercooled liquid water at – 50℃ will freeze adiabatically. ∆G, ∆S of this change?

• Final state might be a mixture of ice and liquid water.
• Liquid water and ice can coexist only at the melting point T, 0℃
  Let’s set the fraction of ice at the final state (x).

  Split the process into

1) ∆G

2) ∆S
