In a reversible process entropy of the system
WebEntropy in Thermodynamics reversibility • all real processes are irreversible • energy losses due to friction are not recoverable • energy never spontaneously moves from a cold object to a hot object • some real processes are approximately reversible • ideal processes may be reversible • a reversible ideal process: • is quasi-static: the process occurs in such away … WebAn ideal thermodynamically reversible process is free of dissipative losses and therefore the magnitude of work performed by or on the system would be maximized. The incomplete …

WebJun 13, 2024 · To measure an entropy change using this definition requires that the process be reversible, which means that the system and surroundings must be at the same … WebSep 12, 2024 · The process is clearly stated as an irreversible process; therefore, we cannot simply calculate the entropy change from the actual process. However, because entropy …
WebWe would like to show you a description here but the site won’t allow us. WebNov 26, 2024 · A reversible process has zero change in entropy. Therefore a reversible process does maximum work. The work done on a heat engine is W = Q c − ( − Q h) where Q c is the heat entering the cold reservoir and Q h is the heat entering the hot reservoir. Given that Q = T Δ S then after a little algebra we get that the efficiency is
