An ideal gas (Cp / Cv = gamma) is taken ...

An ideal gas `(C_p / C_v = gamma)` is taken through a process in which the pressure and volume vary as `(p = aV^(b))`. Find the value of b for which the specific heat capacity in the process is zero.

Text Solution

Verified by Experts

The correct Answer is:
A
`p_V^-b = constant`
`C = R/(gamma - 1)+ R/(1 - (-b))`
`C = 0 , if gamma -1 = -(1 +b)`
`:. b = - gamma`.
