The correct Answer is:
To answer the question regarding the positive value of ΔS (Delta S), we need to analyze what ΔS represents in thermodynamics. ### Step-by-Step Solution: 1. **Understanding ΔS**: - ΔS stands for the change in entropy of a system. Entropy is a measure of the disorder or randomness in a system. 2. **Positive ΔS**: - A positive value of ΔS indicates that the entropy of the system has increased. This means that the system has become more disordered or random. 3. **Implications of Increased Entropy**: - When ΔS is positive, it suggests that the processes occurring in the system lead to a greater number of possible arrangements of the particles. This is often seen in processes such as the melting of ice into water or the vaporization of water into steam, where the molecules have more freedom to move. 4. **Examples of Positive ΔS**: - A common example is the transition of a solid to a liquid (melting) or a liquid to a gas (vaporization). In both cases, the molecules are more disordered in the liquid or gas phase compared to the solid phase. 5. **Equilibrium Consideration**: - At equilibrium, the change in entropy (ΔS) is zero, indicating that there is no net change in disorder. If a system is moving towards equilibrium, ΔS will approach zero. 6. **Conclusion**: - Therefore, a positive value of ΔS indicates that the system is becoming more disordered, which is associated with an increase in randomness. ### Final Answer: The positive value of ΔS indicates that the entropy of the system is increasing, meaning the system is becoming more disordered or random.
