Answer» <P>In thermodynamics, when we're interested at GASES, I know that the work done can be written to be −pdV for a reversible process (p is the pressure of the system, and V is the volume of the system). This is because dW=Fdx=−pAdx=−pd(Ax)=−pdV However, why is it not true ALSO that the work done is −pdV for non-reversible PROCESSES as WELL?
