What is Entropy and the Second Law of Thermodynamics - Definition

Web13 May 2009 · The second process which restores the system into the original state is known as an effacing process. Any process which is not reversible is irreversible. The way to decide whether a process is reversible or irreversible is to apply the only natural law at our disposal which concerns directions, ie the 2 nd law of TD. WebThe 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 solid at 0 K. the gellert group
