Question

Which of the following statement(s) is are correct?

Statement (i): The entropy isolated system with P-V work only, is always a maximized at equilibrium.

Statement (ii): It is possible for the entropy of a close system to decrease substantially in an irreversible process.

Statement (iii): Entropy can be created but not destroyed.

Statement (iv): $\Delta S_{system}$ is zero for reversible process in an isolated system

• A. Statement i, ii, iii
• B. Statement ii, iv
• C. Statement i, ii, iv
• D. All of these

Answer 1

Answer: (C)

Statement i, ii, iv

Statement $\left(I\right)$ - The entropy isolated system with $P-V$ work only is always a maximized at equilibrium.

Statement $\left(II\right)$ - It is possible for the entropy of a close system to decrease substantially in air irreversible process.

Statement $IV$ - delta $S_{system}$ is zero for reversible process in an isolated system.

The above statements are correct.
