A process occurs taking 5kg of mass from state A to state B. The work during this adiabatic process is 5kJ. The change in specific internal energy during this process is 10 KJ/Kg Calculate the heat transfer Q during this process. A second process now takes the system back the original state, with a heat interaction of 30kJ. Calculate the work interaction of the second process in kJ. (The sign of each interaction is important)
