Abstract
A mechanism of bubble stability for a system containing an abritrary number of bubbles in a liquid-gas solution has been recently proposed on a theoretical basis. This mechanism is thought to be related in an essential way to bubble stability in animals. It leads to the prediction that the final equilibrium size for the bubbles decreases as the number of bubbles in the system increases, for the same temperature, total gas content, and pressure in the liquid phase. This prediction has been investigated by introducing 16 bubbles into a volume of liquid-gas solutions, merging them by pairs and after each merging, measuring their final steady-state size. The mean steady-state radius of the bubbles is found to closely compare with the true equilibrium size predicted by a previously developed thermodynamic theory for bubble stability.
