Problem- A) What is the main difference between the isotherms above and d below the critical temperature Tc? Which equation can describe their behavior perfectly and which can describe them only approximately? Why?
B) If you know one isotherm below the critical Tc, how could you get some others?
C) Mix 1000 identical blueberries with 100 identical blackberries. What is the change of entropy? How dose their entropy change, if you put them in the space shuttle, where the volume that they occupy grows 5 times. Why do we not need to use fugacity?
D) Why is it harder to find crystal enthalpy in covalent and metalic crystals then in ionic crystals? Is crystal enthalpy larger in crystal made of benzene or naphthalene?
Any expert will able to provide correct answer for the above question.
