The excess pressure inside a soap bubble is

The excess pressure inside a soap bubble of radius R is (S is the surface tension)

The surface of soap solution is 25xx10^-3Nm^-1 . The excess pressure inside a soap bubble of diameter 1 cm is

The excess pressure inside a soap bubble of radius 6mm is balanced by 2mm column of all of density 800 kgm^(-3) . Find the surface tension of soap solution.

Describe an experiment to demonstrate the excess pressure inside a soap bubble.

The excess pressure inside one soap bubble is three times that inside a second soap bubble, then the ratio of their surface area is:

A 0.02 cm liquid column balances the excess pressure inside a soap bubble of radius 7.5 mm. Determine the density of the liquid. Surface tension of soap solution 0.03 Nm^-1 .

0.04 cm liquid column balances the excess pressure inside a soap bubble of radius 6 mm. Evaluate density of the liquid. Surface tension of soap solurtion = 0.03 Nm^(-1) .

Calculate the height of liquid column required to balance the excess pressure inside a soap bubble of radius 3 xx 10^(-3) m .The density of liquid is 900 kgm ^(-3) and the surface tension of soap solution is 30 xx 10^(-3) Nm^(-1) .

The excess pressure in a soap bubble is thrice that in other one. Then the ratio of their volumes is

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
