SUMMARY
The discussion centers on the concept of entropy change in a device operating at steady state, specifically questioning whether the change in entropy (S2-S1) equals zero. It is established that S2-S1 does not equal zero, as indicated by the equation S2-S1 = s(degree)(T2) - s(degree)(T1) - R ln(p2/p1). This equation demonstrates that entropy change is influenced by temperature and pressure variations, thus confirming that S2-S1 can be non-zero even in steady-state conditions.
