Question

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.

Answer 1

Correct Answer - `-gamma`
`PV^(-a) = k, C = C_(V) + (R )/(1-x), x =- a`
`0 = (R )/((gamma-1)) +(R )/(1+a) rArr b =- gamma`.
