On heating water, bubbles being formed at the bottom of the vessel detach and rise. Take the bubbles to be spheres of radius R and making a circular contact of radius r with the bottom of the vessel. If `rlt ltR` and the surface tension of water is T, value of r just before bubbles detach is: (density of water is `rho_w`)

Take the bubbles to be spheres of radius R and amking a circular contact of radius r with the bottom of the vessel. If r ltlt R , and the surface tension of water is T , value of r just before bubles detatch is : (density of water is rho_(w))

A spherical air bubble of radius r is formed in water. If T be the surface tension of water, the excess pressure insidedhe bubbles is.

When an air bubble rise from the bottom of a deep lake to a point just below the water surface, the pressure of air inside the bubble

When an air bubble rise from the bottom of a deep lake to a point just below the water surface, the pressure of air inside the bubble

An air bubble is formed at depth h below the surface of water. The pressure inside the bubble is- ( P_(0)= atmospheric pressure, r = radius of bubble)

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)
