    Consider two containers AA and BB containing monoatomic gases at the same Pressure (P), Volume (V) and Temperature (T). The gas in A is compressed isothermally to 18\frac{1}{8} of its original volume while the gas BB is compressed adiabatically to 18\frac{1}{8} of its original volume. The ratio of final pressure of gas in BB to that of gas in AA is:
