Example of reversible process thermodynamics
WebAn irreversible process is a thermodynamic process that departs from equilibrium. In terms of pressure and volume, it occurs when the pressure (or the volume) of a system changes dramatically and instantaneously … WebOct 6, 2024 · Solved Examples on Reversible and Irreversible Process Example 1. Calculate the work done when 2 moles of an ideal gas expand reversibly and isothermally from a volume of 500ml to a volume of 2L at 25℃ and normal pressure. Solution 1. Given data, Number of moles (N) = 2 Initial volume \(V_i\) = 500ml = 0.5L. Final volume \(V_f\) …
