Image For process A: log P = γ log V P = Vᵞ, where γ > 1 Therefore, PV⁻ᵞ = constant For a process PVⁿ = constant: C = Cᵥ + R/(1 - n) Here, n = -γ. So, Cₐ = Cᵥ + R/(1 + γ) For process B: P ∝ V Therefore, PV⁻¹ = constant Here, n = -1. So, Cᵦ = Cᵥ + R/(1 + 1) = Cᵥ + R/2 Also, Cₚ = Cᵥ + R Hence, Cₚ > Cᵦ > Cₐ > Cᵥ Official source answer: BONUS because none of the original options matched the calculated relation. For clean upload, Option D has been corrected to the calculated relation Cₚ…
