1， The second law of thermodynamics is incorrect. See figure below for details.

2，The system is isothermal and exchanges heat with a large heat source to keep the temperature constant. Only volume changes are discussed.

3，The problem here is that the actual system is balanced and the second law of thermodynamics judges it to be unbalanced.
