Vedclass · Answer

(A) For an irreversible expansion of a gas against a constant external pressure,the work done is given by the formula $W = -P_{ext} \Delta V$. If the gas expands into a vacuum (free expansion),$P_{ext} = 0$,so $W = 0$. However,in the context of general irreversible expansion,the work is defined as $W = -P_{ext} \Delta V$.
