You are interested in finding the heat added ?Q, the work done ?W, and the change in internal energy ?E for each stage of the Carnot cycle depicted in Figure 13.11. The working fluid is an ideal gas with five degrees of freedom per molecule (γ = 1.4). It starts out at the beginning of stage 1 with pressure p1 = 4 × 105 Pa, volume V1 = 10-3 m3, and temperature T1 = 600 K. It expands isothermally in stage 1 to volume 2V1 and then adiabatically in stage 2 to volume 3V1.
(a) Make a table showing the pressure, volume, and temperature at the end of each of the four stages.
(b) Make a table showing the values of ?Q, ?W, and ?E in joules for each of the four stages.
(c) What is the efficiency of this cycle?
