Web24 nov. 2024 · Bubbles in liquid are essentially air pockets and air is less dense than water. So therefore the bigger bubble contains more air so will rise alot quicker. It’s the same as if u fill two different balloons with different amounts of helium, the one with more helium will rise quicker. How fast does a bubble rise in water? WebAnswer (1 of 3): You specified air bubbles. These form when dissolved air is outgassed from heated liquid. These bubbles usually happen before the boiling temperature is reached. They become larger as they rise for two reasons; reduced overlying pressure allows expansion, and additional volumes o...
