Question

A gaseous mixture consists of 16g of helium and 16 g of oxygen. The ratio `(C_p)/(C_v)` of the mixture is
A. `1.62`
B. `1.59`
C. `1.54`
D. `1.4`

Answer 1

Correct Answer - A
(a) `(n_1+n_2)/(r-1)=(n_1)/(r_1-1)+(n_2)/(r_2-1)`
`(16/4+16/32)/(r-1)=(16//4)/(5/3-1)+(16//32)/(1.4-1)`
`:. gamma=1.62`
