For an ideal gas
\begin{align}
d\epsilon &= \frac{R}{\gamma -1}dT \\
PdV &= -\left(\gamma -1\right)\epsilon \frac{d \rho}{\rho} =
RT -RT\frac{d \rho}{\rho}
\end{align}
Then
\begin{equation}
...
\end{equation}
so that
\begin{align}
dQ &= R\left( 1 + \frac{1}{\gamma-1}\right)dT - \frac{d
\rho}{\rho} P}{\rho} \\
&= \frac{\gamma R}{\gamma-1}dT - \frac{d P}{\rho}
\end{align}
