Proof: entropy in reversible and irreversible process + MCQs

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 WebOct 17, 2016 · Supposing the heat is transferred from surroundings to the system irreversibly, if we want to calculate entropy change of the system we have to find reversible path for the change, so that means that change in entropy for the reversible path found and previous irreversible is the same. WebNov 7, 2024 · Figure 6.5.e1 T-S diagram for a reversible process and an irreversible process with the same initial and final states Solution: (1) Entropy is a state function. The two processes have the same initial and final states, therefore, the same Δ S. (2) From the definition of entropy, the heat transfer in the reversible process can be found from can i not go to school but go to work
