Why is reversible work greater than irreversible work?

WebApr 3, 2024 · Work in general is defined as a product of a force F and a path element ds. Both are vectors and work is computed by integrating over their inner product: w = ∫F ⋅ ds Moving an object against the force of friction as done in the above dissipation experiment is but one example of work: wfriction = ∫Ffriction ⋅ ds WebMay 26, 2024 · Yes, thermodynamics can identify irreversible processes. For a closed system, a process it suffers is irreversible if the change in entropy of the system is greater than the integral of over the process path, where is the temperature at the system boundary (with its surroundings) where the heat transfer dq occurs.
