I have a conceptual question that I am trying to clear up. A reversible process means that the net change in entropy is zero. If we have two scenarios, where case 1 has a ΔS= 0.1 J/K and case 2 has a ΔS= 0.5 J/K. Is it a correct statement to say that case 1 is "less irreversible (i.e., more reversible)" than case 2? Or do I have to think of this in a more binary(black & white) kind of way, where as long as ΔS≠0, the degree of irreversibility is the same?
