Surface charge density of soap bubble of radius `r` and surface tension `T` is `sigma`.If `P` is excess pressure the value of `sigma` is

Excess pressure inside a soap bubble of radius r and surface tension T is

What is the surface energy of a soap bubble of radus r and surface tension T?

The work done in blowing a soap bubble of radius r of the solution of surface tension T will be

If R is the radius of a soap bubble and S its surface tension, then the excess pressure inside is

Excess pressure in a soap bubble of radius r is proportional to:

A soap bubble in air (two surfaces) has surface tension 0.03 Nm^(-1) . Find the excess pressure inside a bubble of diameter 30 mm.

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
