In a reversible process entropy of the system
WebMar 19, 2024 · In an irreversible process, the system itself generates entropy that has to be added to the terms δ Q T representing heat transfer from/to the outside. For example, if a current I passes through a resistor R at temperature T the rate of entropy generation is I 2 R T as measured in units of j o u l e k e l v i n × s e c.

For example you can mix two gases very slowly … WebSep 12, 2024 · A reversible process is a process in which the system and environment can be restored to exactly the same initial states that they were in before the process …
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 WebAug 25, 2024 · If a process occurs in a closed system, the entropy of the system increases for irreversible processes and remains constant for reversible process. It never decreases. I have explained here in short about what has been given in my textbook for entropy.
WebJun 27, 2024 · A reversible process is one where d S u n i v = 0, while d S u n i v > 0 indicates a (spontaneous) irreversible process. In a reversible process, the entropy change of the … WebThis is the entropy change for the system both for the reversible path you devised as well as for the actual irreversible path. In the case of the surroundings, during the irreversible process, its internal energy increased by 3.741 kJ at the constant temperature of 300 K.
