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.
