2 moles of monatomic gas (γ = 3/2) is mixed with 3 moles of diatomic gas (γ = 5/7). Find γ of the mixture here γ = Cp/CV.
Multiple Choice Options
- A 5/3
- B 29/19
- C `11/7
- D 39/29
Step-by-Step Verified Solution
γ_mix = (n1Cp1 + n2Cp2)/(n1Cv1 + n2Cv2) => γ_mix = (2×5R/2 + 3×7R/2)/(2×3R/2 + 3×5R/2) => γ_mix = 29/19
