The interaction between a planar shock wave and a rectangular bubble containing either SF6, He, Ar, or CO2 is studied numerically. It is shown that due to the existing large differences in the molecular weight and the specific heat ratio between these gases, different wave patterns are developed during the interaction process. As expected, the fastest transmitted shock is witnessed in the He case, while the slowest is the transmitted shock wave in the SF6 case.
