Consider the cyclic thermodynamics process ABCA shown in the diagram. Recall Eint = Q + W (First Law of Thermodynamics)
1) Find the net energy transferred to the system by heat during one complete cycle
2) What if the cycle was reversed? That is, the process follows the path ACBA, what is the net energy input per cycle?
3) If Q is negative for the process BC and ?Eint is negative for the process CA, what are the signs of heat(Q), work(W) and change in the internal energy(?Eint) that are associated with each of the three processes?
