Equal volumes of monoatomic and diatomic...

Equal volumes of monoatomic and diatomic gases at same initial temperature and pressure are mixed. The ratio of specific heats of the mixture `(C_(p)//C_(v))` will be

A

1

B

2

C

`1.67 `

D

`1.2`

Text Solution

Verified by Experts

For monoatomic gas, `gamma _(1) = ( C _(P))/( C _(gamma)) = 1. 67 ,` For diatomic gas, `gamma_(2) = ( C _(p))/( C _(v)) = 1. 40`
`gamma _(1) : gamma _(2) = ( 1. 67)/(1 . 40) = 1.19 : 1`
