According to the entropy theorem, the entropy of an isolated system can never decrease and will remain constant only when the process is reversible.
Detailed Solution for Test: 2nd and 3rd Law of Thermodynamics and Entropy - Question 6

The second law of thermodynamics, which states that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. According to this law, the entropy of an isolated system can indeed never decrease; it will either increase or remain constant if the system is undergoing a reversible process.

Therefore, the correct answer is: True
