ABSTRACT
For example, the inner pressures of bubbles whose diameters are 1 μm and 100 nm are 3.87 and 29.7 atm, respectively, using Eq. (1.2) (surface tension of water at 20°C: 72.8 mN/m, the surrounding pressure of bubble is 1 atm). With decreasing bubble size, the pressure in the bubble increases. With decreasing bubble size, the partial pressure of dissolved gas component, that is, the driving force of dissolution, increases and the gas dissolves easily.
