If one mole of a monatomic gas (gamma=5/...

If one mole of a monatomic gas `(gamma=5/3)` is mixed with one mole of a diatomic gas `(gamma=7/5),` the value of gamma for mixture is

A

`1.40`

B

`1.50`

C

`1.53`

D

`3.07`

Text Solution

Verified by Experts

The correct Answer is:
B

(b) `(n_1+n_2)/(gamma-1)=(n_1)/(gamma_1-1)+(n_2)/(gamma_2-1)`
Here, `n_1=n_2=1, gamma_1=2/5, gamma_2=5/3`
