3. A hypothetical element , transforms to phase from phase at 55K and 1atm. Consider and to be pure crystalline phases. Find the following: a. What is the entropy of transformation, S0(), at 55K and 0K at 1atm pressure? (Hint: Use 3rd Law of Thermodynamics) b. What is the change in Gibbs Free Energy, G0(), at 55K and 0K at 1atm ? c. What is the enthalpy of transformation, H0(), at 55K and 0K at 1atm pressure. d. What is the volume difference between the two phases. Which one has the higher density? Explain your answer. Given: The heat capacities of are: cP0,=8.8105T3Jmol1K1cP0,=2.38104T3Jmol1K1 3. A hypothetical element , transforms to phase from phase at 55K and 1atm. Consider and to be pure crystalline phases.
