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. WebMar 16, 2024 · Rather than answer the question numerically I have outlined the four different cases, reversible / irreversible and isothermal / adiabatic. In adiabatic changes no energy is transferred to the system, that is the heat absorbed or released to the surroundings is zero. 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.
