Questions & Step-by-Step Solutions
What happens to the entropy of a system when it undergoes a reversible process?
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Know what a reversible process is. A reversible process is a process that can be reversed without leaving any change in the system and surroundings.
Step 3: Recognize that during a reversible process, the system can exchange energy with its surroundings without increasing the total disorder.
Step 4: Realize that in a reversible process, the total entropy of the system and its surroundings does not change.
Step 5: Conclude that the entropy of the system remains constant during a reversible process.
