The diameter of a gas bubble formed at the bottom of a pond is `d = 4 cm`. When the bubble rises to the surface, its diameter tension of water `= T = 0.07 Nm^(-1)`

The diameter of an air-bubble formed at the bottom of a pond is d=4mum , when the bubble rises to the surface, its diameter increases n=1.1 times. If expansion of air bubble is assumed to be isothermal and atmospheric pressure to be standard. How deep the pond at the spot is [surface tension of water 0.075(N)/(m) ]

An air bubble of diameter 1 mm is formed at the bottom of a lake and when it rises to the surface of the water, its diameter becomes 2 mm. If the atmospheric pressure is 760 cm of mercury, then find the depth of the lake. (Density of mercury = 13.6g*cm^(-3) )

A spherical air bubble is formed in water at a depth of 1.2 m from the surface. The diameter of the bubble is 0.6 mm and surface tension of water is 0.073 Nm^(-1) . Calculate the pressure inside . Atmospheric pressure = 10.3m of water.

The capillary rise in a tube of diameter 1mm when surface tension of water is 0.06 Nm^-1 is

What would be the gauge pressure inside an air bubble of 0.2 mm radius situated just below the surface of water ? Surface tension of water is 0.07 "Nm"^(-1).

If the diameter of a soap bubble is 10 mm and its surface tension is 0.04 Nm^-1 , find the excess pressure inside the bubble.
