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

Options

A. `C_(v) = 5 cal//mol K`
B. `c_(v) or s_(v) = 0.45 cal//mol K`
C. `C_(p)=(R gamma)/(gamma-1)`
D. `C_(v) = (R )/((gamma-1))`

Answer

B

Explanation

The Poisson's ratio ………..
`(C_(p))/(C_(v)) = 1.4 = gamma`
`C_(p)-C_(v)=R`
`gammaC_(v)-C_(v)=R`
or `C_(v) = (R )/((gamma-1))` and `C_(p) - (C_(p))/(gamma) = R or C_(p) = (R gamma)/(gamma-1)`
`C_(v) = (2)/(0.4) = 5 cal//mol K`
Also `c_(v) or sv = (2)/(0.4xx32) = 0.15 cal//mol K`
