Entropy _________ .(Choose all that are correct.)a. dispersesb. is a measure of disorderc. always increases, overalld. is energy

Key Concepts: Entropy Explanation: Entropy is a thermodynamic property that is related to disorder or randomness, and is typically denoted as S. It is a measure of the number of ways in which the particles of a system can be arranged without changing the overall energy of the system. Step by Step Solution: Step 1. Entropy is a measure of disorder or randomness in a system, so option (b) is correct. Step 2. Entropy is related to the number of ways in which particles can be arranged without changing the overall energy of the system. In general, the number of ways in which particles can be arranged increases as the system becomes more disordered, so option (a) is also correct. Step 3. According to the second law of thermodynamics, entropy always increases over time, so option (c) is correct. Finally, option (d) is incorrect because entropy is not itself a form of energy, but rather a property related to the arrangement of particles within a system. Final Answer: Options (a), (b), and (c) are correct.
