In thermodynamics, during a reversible process, the net entropy change must equal zero, which allows for the individual entropy changes of the system and surroundings to vary as long as their total remains zero. This means that while the entropy of the system may increase or decrease, the entropy change of the surroundings will adjust accordingly to maintain the overall balance. The key takeaway is that in a reversible process, the sum of the entropy changes of both the system and surroundings is strictly zero.

Yes. The entropy change of the system or the surroundings can be greater or less than zero in a process. But they cannot sum to less than zero. In a reversible process, they sum to zero.Chronos000 said:Homework Statement
For a reversible process, while the net entropy change must be zero, does this mean that the entropy of the system and surroundings can change as long as they amount to zero?
