... pressure, it is offered zero resistance. Hence, no work is one by or upon the gas. If this sounds unconvincing, consider ∫PextdV. Since the external pressure is constant, we take it out of the integral, and since the external pressure is zero, the whole term is zero by itself. w, then, too becomes z ...
