Do Air Bubbles Increase Volume? Do air bubbles increase volume? When an air bubble rises in water, its mass remains the same, but density decreases and volume increases. Do bubbles increase volume? Thus, when a bubble rises from below the surface it encounters less pressure. This causes the volume to increase and the bubble rises
