WebMay 5, 2024 · 1 Answer Sorted by: 3 No. For a cyclic process, the system returns to its original state at the end of the process, so its entropy change is zero. But for the surroundings, that are typically envisioned as being comprised of ideal reservoirs, the entropy change is not necessarily zero.

WebIn general, the temperature of the system may change during a process. If the process is reversible, the change in entropy is defined as S f−S i=∫ if= T Q In an adiabatic reversible process, no heat is given to the system. Therefore, entropy of the system remains constant in such a process. Video Explanation WebQuestion: ndicate whether each statement is true or false. Drag the appropriate sentences to their respective bins Reset Help If a system undergoes a reversible process, the change in entropy of the system is exactly matched by an equal and opposite change in the entropy of the surroundings. dallas cowboys box score yesterday https://chantalhughes.com
