A polytropic process for an ideal gas is represented by equation PVn = constant. If g is ratio of specific heats% (CpCv), then value of n for which molar heat capacity of the process is negative, is given as:

C = Rγ-1-Rn-1 = R(n-γ)(n-1)(γ-1)C is negative if γ > n > 1.

Detailed Solution

$C = \frac{R}{γ - 1} - \frac{R}{n - 1} = \frac{R (n - γ)}{(n - 1) (γ - 1)}$

C is negative if $γ > n > 1$ .
