Write out the microstates for a more efficient ADDI and SW using the modifications on the LC-5000 datapath. For each microstate, give the control signals used (see the example). Signals irrelevant to the state can be omitted and will be assumed to be zero. You will lose points for an inefficient answer!

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
