Irreversible work

WebNov 16, 2024 · In a quasistatic process (reversible), the difference between the external pressure and the internal pressure is infinitesimal for each infinitesimal change in the volume of the system. P e x t = P i n t ± d P, As you know that the term for work in terms of pressure is given by, d W = P d V. WebSep 9, 2024 · In a reversible process, every intermediate state between the extremes is an equilibrium state, regardless of the direction of the change. In contrast, an irreversible process is one in which the intermediate states are not equilibrium states, so change occurs spontaneously in only one direction.

WebAug 25, 2024 · An "irreversible isobaric process" is the term we use to describe a situation in which a gas is at an initial pressure P 0 and we suddenly drop (or raise) the force per unit area exerted on the gas by the inner face of the piston to P 1 ≠ P 0, and hold it at this value while the piston moves and the gas re-equilibrates. 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 6, 2024 · The explanation is as following. "More work is obtained when the expansion is reversible because matching the external pressure to the internal pressure at each stage of the process ensures that none of the system’s pushing power is wasted. WebJun 13, 2024 · The work done under such conditions is reversible work; an arbitrarily small change in the relative pressures can reverse the direction in which the piston moves. We summarize these conditions by saying that reversible pressure–volume work can occur …
