Thermodynamic Processes

A polyatomic gas $(\gamma = 4/3)$ is compressed to $\left(\frac{1}{8}\right)$ th of its volume adiabatically. If its initial pressure is $P_0$ , its new pressure will be

Show answer and solution

Answer: (d)

Adiabatic: $P_2 = P_0\left(\frac{V_1}{V_2}\right)^\gamma$ .
$P_2 = P_0 \cdot 8^{4/3} = 16P_0$
So the answer is (d) $16P_0$ .
