  • $\begingroup$ Thank you for the answer. I already knew that entropy is a system property which makes its change independent of the transformation. But, in the previous question I received a comment by @ChetMiller: "Irreversible and reversible isobaric processes do not go between the same initial and final states for adiabatic isobaric processes". So, how can we justify the fact that the entropy change for a system in an irreversible isobaric transformation is the same as in a reversible isobaric transformation? $\endgroup$ Commented Dec 27, 2024 at 8:34
  • $\begingroup$ @Bml Any type of irreversible adiabatic transformation can’t connect the same two equilibrium states as a reversible adiabatic transformation because the entropy generated in the irreversible transformation becomes “trapped” in the system. The only way the system can get rid of the generated entropy is by transferring it to the surroundings in the form of heat, which by definition of adiabatic is impossible. The second law is satisfied since the total entropy change is greater than zero $\endgroup$ Commented Dec 27, 2024 at 10:24
