During an adiabatic process, the pressure P of a fixed mass of an ideal gas changes by ΔP and its volume V changes by ΔV. The value of $$\frac{V}{V}$$ is given by

A

- $$\gamma \frac{\triangle P}{P}$$

B

$$\frac{1}{\gamma}$$ $$\frac{\triangle P}{P}$$

C

$$\frac{1}{\gamma^{3}}$$ $$\frac{\triangle P}{P}$$

D

$$\frac{\triangle P}{P}$$
