if R is the molar gas constant and `gamma=C_(P)//C_(V),` then `C_(V)` is equal toA. `R//gamma`B. `gammaR`C. `(2R)/(gamma-1)`D. `(R)/(gamma-1)`

Answer» Correct Answer - D
`C_(p)_C_(V)=R`
`(C_(p)-R)/(C_(V))=(C_(V))/(C_(V))+1`
`(C_(p))/(C_(V))-(R)/(C_(V))=1`
`gamma-(R)/(C_(V))=1`
`gamma-1=(R)/(C_(V))" "thereforeC_(V)=(R)/(gamma-1)`
