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

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

B

`(gamma)/(RM)`

C

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

D

`(gamma RM)/(gamma+1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(P)-C_(V)=R/M`
`rArr C_(P)-C_(P)/gamma=R/M [[ :'C_(P)/C_(V)=gamma],[rArr C_(V)=C_(P)/gamma]]`
`rArr C_(P) (1-1/gamma)=R/M`
`rArr C_(P)=(gammaR)/(M(gamma-1))`
