Excess Pressure In An Air Bubble Inside Liquid

Give the expression for the excess pressure in an air bubble inside the liquid.

Excess pressure inside a bubble is

The excess pressure inside an air bubble of radius 1 mm formed inside water is (S.T=0.072N//)

The excess pressure inside an air bubble of radius 1 mm formed inside water is (S.T=0.072N//)

The excess pressure inside an air bubble of radius r just below the surface of water is P_(1) . The excess pressure inside a drop of the same radius just outside the surface is P_(2) . If T is surface tension then

The excess pressure inside an air bubble of radius r just below the surface of water is P_(1) . The excess pressure inside a drop of the same radius just outside the surface is P_(2) . If T is surface tension then
