Please solve part b : 4

Р2. a) Consider a process involving an ideal diatomic 3 mol, following p = aV, where gas with n = a = 1 × 10° Pa/m³ is a constant. The gas ex- pands from volume V; = 1m³ to Vf = 4m³. Find the %3D P2 В (i) work done on the gas. (ii) heat entering the gas. 1 (iii) change in the internal energy of the gas. b) Now consider the cycle depicted in the figure, involving the same amount of gas as in the previous part. A → B is the process described in the previous subtask, B → C an isochor and C → A an isobar. Additionally, V2/V1 = n = 4 and V = 1 m3. Find the A C Pi 3 i) work done by the gas during one loop of the cycle. Vị V2 V ii) thermal efficiency of the cycle. iii) maximum theoretical efficiency of a Car- not cycle having the same temperature extrema as in this cycle. iv) coefficient of performance of the cycle, if it were used as a refrigerator .
