As we have learned

Slope of Adiabatic curve -

\because PV^{\gamma }= constant

slope =\frac{dP}{dV}

 

- wherein

\frac{dP}{dV}= -\gamma \frac{P}{V}

 

 Slope = \frac{dP}{dV} = - \gamma \left [ \frac{P}{V} \right ]\\\\ specific \: \: heat = C = \frac{\Delta Q}{m \Delta T} = \frac{0}{m \Delta T} = 0 \\\\ PV^{\gamma } = constant \: \: \: \: using \: \: PV= RT\\\\ we \: \: get \\\\ TV^{\gamma -1}= cost
