A monatomic ideal gas is at an initial pressure of 1.54 atm and 76.0 cm3. The gas undergoes an isochoric increase in pressure to 2.31 atm, then an isobaric expansion to 114 cm3. Pressure is reduced isochorically to the original pressure before an isobaric compression returns the gas to its initial values. For 1.95 moles of the gas, complete the following:
a) Generate a sketch of the PV diagram, with values clearly represented.
b) Find the heat absorbed and heat rejected during each cycle.
c) Find the work done in one cycle. d) Calculate the efficiency of the heat engine.
e) Determine the minimum and maximum temperatures during the cycle.
f) Calculate the Carnot efficiency of the heat engine.
g) Find the maximum work that can be done by a Carnot engine that absorbs heat found in part b.
h) Determine the coefficient of performance of a Carnot refrigerator operating between the temperature found earlier.
i) Determine the coefficient of performance of the system if operated as a heat pump.
