Entropy decreases in irreversible processes
Entropy is constant in reversible processes
Both a and c are true
Questions & Step-by-Step Solutions
Which of the following statements is true about entropy?
Correct Answer: a and c
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Learn about reversible processes. In a reversible process, the system can return to its original state without any changes in the surroundings.
Step 3: Know that in reversible processes, the total entropy of the system and surroundings remains constant.
Step 4: Identify the statements given in the question. Look for statements that mention entropy as a measure of disorder and its behavior in reversible processes.
Step 5: Determine which statements are true based on your understanding of entropy and reversible processes.
