One mole of monatomic gas undergoes a Carnot cycle with TH = 400 ∘C and TL = 220 ∘C. The initial pressure is Pa = 8.5 atm (see Figure 20-7 in the textbook). During the isothermal expansion, the volume doubles.

Determine Q for each segment of the cycle.

Determine W for each segment of the cycle.

Determine ΔEint for each segment of the cycle.
