Container divided by frictionless adiabatic wall: reversible or irreversible process?
I have encountered an issue in the following physical situation. Consider a rigid, thermally insulated container divided by a barrier parallel to its base into two parts, left and right, each containi …

Container divided by adiabatic wall with mass and friction: why is it a quasi-static process?
Thanks to the help of @ChetMiller, the following fact is essentially concluded in this thread. Consider a rigid, thermally isolated container divided by a massless barrier parallel to its base into tw …

Why is the entropy change for a system in irreversible transformations the same as in revers...
From the 1st Law of Thermodynamics $\delta Q = \mathrm{d}U + \delta W$, and since $\delta W = 0$ for an isochoric reversible process, we have $\delta Q_{\mathrm{reversible}} = \mathrm{d}U = n c_V \mathrm … From the 1st Law of Thermodynamics $\delta Q = \mathrm{d}U + \delta W$, and since $\delta U = 0$ for an isothermal reversible process, we have $\delta Q_{\mathrm{reversible}} = \delta W = p \mathrm{d}V …
