I understodod the question as: "let us consider a system at equilibrium, I can compute its entropy as a function of its state variables, what is the value of this entropy when the volume tends to zero?". I think this is a fair question and that obviously the answer will depend on the volume. | |

The second law says not that the entropy doesn't want to drop to zero; it says that it never drops. Compression of a gas is a mundane, allowed thing; a decrease of the entropy is not possible. They're completely different things. | |
