Consider e.g. an ideal gas that is expanding slowly while kept at constant … WebSep 19, 2024 · Whether a process is reversible or irreversible, ΔU = q + w. Because U is a state function, the magnitude of ΔU does not depend on reversibility and is independent of the path taken. So Work done in a reversible process is always equal to or greater than work done in a corresponding irreversible process: w rev ≥ w irrev.

In the physical realm, many irreversible processes are present to which the inability to achieve 100% efficiency in energy transfer can be attributed. The following is a list of spontaneous events which contribute to the irreversibility of processes. • Ageing (this claim is disputed, as aging has been demonstrated to be reversed in mice. NAD+ and telomerase have also been demonstrated to reverse ageing.)

WebAnswer: No. Workdone in reversible is always more than the workdone in irreversible. The reason is the system has to work against the gradual higher external pressure in reversible condition. Whereas the external pressure is constant, no rising in irreversible condition, hence work is less. norm glasgowWebMay 30, 2024 · In this irreversible adiabetic process, only the work done on the system will be = − P e x t d V. Because in a reversible process we actually consider P e x t = P i n t + d P, and hence we neglect the d P d V term as it is negligible.
