Question

If one mole of a monatomic gas (γ = 5/3) is mixed with one mole of a diatomic gas (γ = 7/3), the value of g for the mixture is(a) 1.40(b) 1.50(c) 1.53(d) 3.07

Answer 1

Answer:

B) 1.50

Explanation:

For monoatomic gas -

Cv = 3/2RT

Cp = 5/2RT

For diatomic gas  -

Cv = 5/2RT

Cp = 7/2RT

Thus for mixture of 1 mole each  will give -

Cv = 3/2RT+5/2RT/2

Cp=5/2RT+7/2RT/2

Cp/Cv = 3RT/2RT

= 1.5

Thus, the value of g for the mixture is 1.5
