For an adiabatic expansion of an ideal gas, the fractional change in its pressure is equal to (where $γ$ is the ratio of specific heats):

Answer:

Solution:

$\Rightarrow P V^{γ} =$ constant

Differentiating,

$\Rightarrow \frac{d P}{d V} = - \frac{γ P}{V}$

$\Rightarrow \frac{d P}{P} = - \frac{γ d V}{V}$
