Question: In a reversible process, the change in entropy of the universe is:

Options:

Correct Answer: Zero

Solution:

In a reversible process, the change in entropy of the universe is zero, as the system and surroundings are in equilibrium.

In a reversible process, the change in entropy of the universe is:

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.

Entropy in Reversible Processes – In a reversible process, the total change in entropy of the universe (system + surroundings) is zero, indicating that the process can be reversed without any net change.
Equilibrium – In reversible processes, the system and surroundings are in thermodynamic equilibrium, which is essential for the entropy change to be zero.
