Why is there no work in a free and adiabatic expansion of a gas?
Apr 16, 2024 · I recently came across the topic of irreversible expansion in thermodynamics. Suppose we have a container of gas with a piston (not mentioned whether massive or not), …
thermodynamics - Why is entropy change in an irreversible …
Sep 30, 2020 · The proof that an irreversible adiabatic process has an associated nonzero entropy change starts from the observation that the terminal states for reversible and …
