Average value of poisson's ratio for a m...

Average value of poisson's ratio for a mixture of `2` mole of each gas `A` and `B` is `1.66`, then

A

Gases are mono-atomic

B

Gases are diatomic

C

Average molar heat capacity at constant volume is `4 cal`

D

Average molar heat capacity at constant `V` is `3cal`

Text Solution

Verified by Experts

`gamma` for mono-atomic is `1.66`
`:. C_(V) = (3R)/(2),C_(P) = (5)/(2)R`
`C_(V_(M)) =(2xx(3R)/(2)+2xx(3R)/(2))/(4):.C_(V)=3cal`
`C_(P_(M)) =(2xx(5R)/(2)+2xx(5R)/(2))/(4):.C_(P)=5cal`
