Efficiency
An ideal diatomic gas is used in a reversible heat cycle. Thegas begins in state A with pressure 100 kPa, temperature300 K, andvolume 0.50 L. It first undergoes an isochoric heating to state Bwith temperature 900 K. That is followed by an isothermal expansionto state C. Finally, an isobaric compression that returns the gasto state A.
(a)Determine the pressure, volume, and temperature of stateB.
(b)Determine the pressure, volume, and temperature of stateC.
(c)Compute the work and heat exchanged with the gas going fromstate A to B.
(d)Compute the work and heat exchanged with the gas going fromstate B to C.
(e)Compute the work and heat exchanged with the gas going fromstate C to A.
(f)Compute the efficiency of the heat cycle.
