For a gas having molar mass M, specific ...

For a gas having molar mass `M`, specific heat at constant pressure can be given as:

A

`(gammaR)/(M(gamma-1))`

B

`gamma/(RM)`

C

`M/(R(gamma-1))`

D

`(gammaRM)/(gamma+1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(P)-C_(v)=R`
`:. C_(P)-C_(v)=R/M`
Also `(C_(p))/(C_(v))=gamma`
`:. C_(p)-(C_(p))/(gamma)=R/M`
`:. C__(p)=(R.gamma)/(M(gamma-1))`
