Thermodynamic Processes

A monoatomic gas is suddenly compressed to $(1/8)$ th of its initial volume adiabatically. The ratio of the final pressure to initial pressure of the gas is $(\gamma = 5/3)$

Show answer and solution

Answer: (a)

Adiabatic: $\frac{P_2}{P_1} = \left(\frac{V_1}{V_2}\right)^\gamma$ .
$\frac{P_2}{P_1} = 8^{5/3} = 2^5 = 32$
So the answer is (a) 32.
