Two processes have been chosen to show the difficulty of attributing a physical significance to the first law - dU=dW+dQ, since it is not possible to separate the energetic exchange between two subsystems, dividing it into work - dW, and heat - dQ, with an energetic significance (attributed to each one of these terms), even if a "quasi-static" transformation is assumed. By analysing these processes we have shown that the First Law does not possess the significance commonly attributed to it. The analysis developed herein completes one recently published .
