Statement 2: The dissolution of gases in water proceed with a negative value of $\Delta S$

• A. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
• B. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
• C. Statement 1 is True, Statement 2 is False
