One mole of an ideal diatomic gas follows the cycle ABCDA as shown in the figure. P₁ = 1.0 atm and V₁-12.3 L. P₂ = 2.0 atm and V₂=24.6 L. The temperatures are TÃ= 150 K, TB = 300 K, Tc = 600 K, and TD = 300 K, respectively. R = 8:314 J/(mole K), 1 atm = 1.013 x 105 Pa, 1 L = 10-³ m³. Show the physics approach and all steps. 10 points P, atm B с | P₂ P₁ A 1 V₁ D I V₂ V, L

(a) During the change from A -> B: Calculate the work done, the change in internal energy, and the Q transferred between the system and the surroundings. Has the internal energy increased or decreased? Does heat enter or leave the system? (b) During the change from B -> C: Calculate the work done, the change in internal energy, and the Q transferred between the system and the surroundings. Has the internal energy increased or decreased? Does heat enter or leave the system? (c) During the change from C -> D: Calculate the work done, the change in internal energy, and the Q transferred between the system and the surroundings. Has the internal energy increased or decreased? Does heat enter or leave the system? (d) During the change from D -> A: Calculate the work done, the change in internal energy, and the Q transferred between the system and the surroundings.
