The change in Entropy is zero for _____?

اینٹروپی میں تبدیلی _____ کے لئے صفر ہے؟

Reversible isobaric processes

Reversible adiabatic processes

Reversible isothermal processes

None of these

In a reversible adiabatic process, no heat is exchanged with the surroundings (Q = 0), so the change in entropy (ΔS) is zero.

Entropy change is linked to heat transfer, and since no heat enters or leaves, entropy remains constant.
