Recall the case of an adiabatic free expansion -- the temperature does not change at all, no work is done, but the volume increases. We now introduce a property called entropy, and give it the symbol "s". We will use entropy change as a measure of how ... WebIn case of an adiabatic process, irreversible expansion of a gas occurs as ∆U = -P ex ∆V, where P ex is the external pressure against which the expansion happens. So what does all this mean in terms of work? Well, suppose we have a volume of gas of 1 m 3 at 273 K and 10 atmospheres. We decide to expand this volume to a final pressure of 1 ...
