A monoatomic gas having $\displaystyle \gamma=\frac{5}{3}$ is stored in a thermally insulated container and the gas is suddenly compressed to $\displaystyle \left(\frac{1}{8}\right)^{\text {th }}$ of its initial volume. The ratio of final pressure and initial pressure is: ( $\displaystyle \gamma$ is the ratio of specific heats of the gas at constant pressure and at constant volume)
