... the adiabatic path and w for the non-adiabatic path. q = wad – w Finally, from the first law of thermodynamics also follows that the internal energy of an isolated system cannot change. Because for an isolated system there is w = 0 and q = 0 and with ΔU = q + w it follows that ΔU = 0. The state of a ...
