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.

WebNov 1, 2008 · So, the work done in irreversible processes will, in general, be less than the integral of P dV. You have equality in the quasistatic case, even if the process is irreversible (but such processes can always be realized in a reversible way). In some books reversible volume pressure work is defined to be any process in which the equality (3) holds.

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. ears armour
