The poisson's ratio for `O_(2)` is `1.4`. Which of the following are correct for `O_(2)`?

Options

A. `C_(v)=R/(gamma-1)`
B. `C_(v)=0.156 cal`
C. `C_(p)=(gammaR)/(gamma+1)`
D. `C_(V_(m))=5 cal`

Answer

C

Explanation

`(C_(P))/(C_(v))=1.4 =gamma`
`C_(P)-C_(v)=R`
`:. gammaC_(v)-C_(v)=R`
`:. C_(v)=R/(gamma-1)`
and similarly `C_(p)-(C_(p))/(gamma)=R`
`:. C_(P)=(gammaR)/(gamma-1)`
`:. C_(V_(m))=2/0.4=5 cal`
alos, `C_(v)=2/(0.4xx32)=0.156 cal`
