The ratio between the specific heats of ...

The ratio between the specific heats of an ideal gas is `gamma`. Show that the number of degrees of freedom of the gas molecules is `n=2/(gamma-1)`.

Text Solution

Verified by Experts

`C_v=n/2R,C_p=C_0+R=n/2R+R=(n/2+1)R`
`thereforegamma=C_p/C_v=(n/2+1)/(n/2)=1+2/n`,
or,`2/n=gamma-1or,n=2/(gamma-1)`
