The slope of an adiabatic curve on a P-V diagram, compared with that of an isothermal curve at the same point, is
Answer: (D) $\gamma$ times
Concept. Differentiate each law.
Step 1. Isothermal. $PV = $ const: $\dfrac{dP}{dV} = -\dfrac{P}{V}$.
Step 2. Adiabatic. $PV^\gamma = $ const: $\dfrac{dP}{dV} = -\gamma\dfrac{P}{V}$.
Answer. $\gamma$ times (Option D).
