For a monatomic gas, calculate Cp/Cv.

1. (a) Cp/Cv = 1.67
2. (b) Cp/Cv = 1.40
3. (c) Cp/Cv = 1.33
4. (d) Cp/Cv = 1.29

Correct answer: (a) Cp/Cv = 1.67

Solution

For a monatomic gas, the degrees of freedom are 3. Using the relation γ = Cp/Cv = (f+2)/f, where f is the degrees of freedom, γ = (3+2)/3 = 1.67.
