WebHowever, because entropy of a system is a function of state, we can imagine a reversible process that starts from the same initial state and ends at the given final state. Then, the entropy change of the system is given by Equation 4.10, Δ S = ∫ A B d Q / T. Solution 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.

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.
