One reason that driving lends itself to aggressive behavior is:
A. Adrenaline builds up as you drive a car
B. Stagnant air in the car causes lightheadedness
C. Drivers feel empowered by anonymity
D. Drivers feel burdened by rules and regulations

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?
