Physics

A monatomic ideal gas is at an initial pressure of 1.54 atm and76.0 cm3. The gas undergoes an isochoric increase in pressure to2.31 atm, then an isobaric expansion to 114 cm3. Pressure isreduced isochorically to the original pressure before an isobariccompression returns the gas to its initial values. For 1.95 molesof the gas, complete the following:

a) Generate a sketch of the PV diagram, with values clearlyrepresented.

b) Find the heat absorbed and heat rejected during eachcycle.

c) Find the work done in one cycle. d) Calculate the efficiencyof the heat engine.

e) Determine the minimum and maximum temperatures during thecycle.

f) Calculate the Carnot efficiency of the heat engine.

g) Find the maximum work that can be done by a Carnot enginethat absorbs heat found in part b.

h) Determine the coefficient of performance of a Carnotrefrigerator operating between the temperature found earlier.

i) Determine the coefficient of performance of the system ifoperated as a heat pump.
