WebAccording to the Boltzmann equation, the entropy of this system is zero. S = k ln W = k ln ( 1) = 0. This limiting condition for a system’s entropy represents the third law of thermodynamics: the entropy of a pure, perfect crystalline substance at 0 K is zero. Careful calorimetric measurements can be made to determine the temperature ... WebThe solution is at boiling point. A The solution is at boiling point. The solution is undergoing a phase change. B The solution is undergoing a phase change. The velocity of molecules in the solution is increasing. C The velocity of molecules in the solution is increasing.
Web12 hours ago · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as … WebJan 25, 2024 · The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, Suniv > 0. If Δ Suniv < 0, the process is nonspontaneous, and if Δ Suniv = 0, the system is at equilibrium. The third law of thermodynamics establishes the zero for entropy as that of a perfect, pure crystalline …
