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