2-2) Decrease in Pressure
Mechanism of How Air Bubbles Are Generated
In general, the higher the gas pressure (partial pressure), the more the gas dissolves into a liquid (Figure 3). Conversely,if a gas at saturated solubility is at a high pressure, bubbles will form when the pressure is decreased.
Note: 1 atmosphere (1 atm) = 1.013 × 105 Pa
