Question

If one mole of a monoatomic (γ = 5/3) gas mixed with one mole of a diatomic gas (γ = 4/3) then the value of γ for the mixture is :

(a) 1.53

(b) 1.40

(c) 1.50

(d) 3.07

Answer 1

Correct option (c) 1.50

Explanation:

For Meyer’* formula Cp − Cv = R

Hence, for monoatmic gas Cv = 3/2 R and

for diatomic gas, Cv = 5/2 R and average
