The volume of an air bubble becomes 3 times
WebWhen more air is pushed into the bubble it expands i.e. its radius increases and we know that excess pressure in a bubble is inversely proportional to the radius of the bubble. So the pressure inside the bubble decreases as we push more air into it. So the correct choice is 'A'. Solve any question of Mechanical Properties Of Fluids with:-

The volume of an air bubble is doubled as it rises from the bottom of a lake to its surface. WebAug 16, 2024 · The plot presented in Fig. 7 indicates that the bubble with the smaller volume (V 0 = 0.0017 µL) has enlarged almost 70-fold, i.e., almost five times more than has the bubble with a close size in 50% ethanol solution. The bubble with a larger size (1 mm) has grown by nearly three times.

If the surface temperature of the sea is 20.0°C, what is the volume of the bubble just before it breaks the surface? [in]cm3
WebDec 5, 2024 · That's because the gas bubble is less dense than the liquid surrounding it, so it should rise to the top of the tube (just as air bubbles in a glass of sparkling water will rise to the top).
WebArun. 25757 Points. 4 years ago. The ratio of the volume of the air bubble at the top to the bottom, V'/V = 6, V' = 6V. The ratio of the density of the mercury to that of the lake water, p'/p = 10/3. => p' = (10/3) p. Now, the pressure exerted at the surface is equal to 75cm of mercury, so the depth = 0.75m. The pressure exerted at the bottom ... jeannine lacroix karlsruheWeb12 A bubble of air of volume 5.0 mm.is under water. The bubble is at a depth where the pressure of the air inside the bubble is four times atmospheric pressure. The temperature of the air in the bubble stays the same as it rises to the surface.
