Answer the highlighted part
One kilogram of a diatomic ideal gas undergoes the following four-step process starting at Point A (100 kPa, 300K, 5 m³):

- **A -> B**: Isothermal compression to 1 m³.
- **B -> C**: Isobaric expansion to 900K.
- **C -> D**: Adiabatic expansion to the original volume of 5 m³.
- **D -> A**: Isochoric process to the original pressure of 100 kPa.

### Tasks:

(a) Determine P, V, and T for points A, B, C, and D.

(b) What is ΔU, Q, W, ΔH, and ΔS for each process of the cycle?

(c) What is the efficiency of this cycle?

(d) Sketch a P-V diagram and T-S diagram, indicating P, V, T for all points & ΔU, Q, W, ΔH, and ΔS for each leg.

(e) Repeat problem one for a monoatomic ideal gas. Compare the thermal efficiency of a monoatomic ideal gas to the thermal efficiency of a diatomic ideal gas for this same cycle.
