Questions & Step-by-Step Solutions
In a reversible process, the change in entropy of the universe is:
Step 1: Understand what a reversible process is. A reversible process is one that can be reversed without leaving any change in the system and surroundings.
Step 2: Know what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 3: Recognize that in a reversible process, the system and its surroundings are in equilibrium. This means there is no net change in energy or disorder.
Step 4: Since the system and surroundings are in equilibrium, the total change in entropy (the measure of disorder) for the universe (system + surroundings) is zero.
Step 5: Conclude that in a reversible process, the change in entropy of the universe is zero.
