Find the capillary pressure
(a) in mercury droplets of diameter `d = 1.5 mu m` ,
(b) inside a soap bubble diameter `d = 3.0 mm` if the surface tension of the soap water solution is `alpha = 45 mN//m`.

Find the free energy of the surface layer of a mercury droplet of diameter d = 1.4 mm , (b) a soap bubble of diameter d = 6.0 mm if the surface tension of the soap water solution is equal to alpha = 45 mN//m .

What is the excess of pressure inside a soap bubble of radius 3cm if the surface tension of the soap solution is 30 dyn/cm ?

Calculate the excess inside a soap bubble of radius 5mm, given surface tension of soap solution 30 dyne/cm.

Energy required to form a soap bubble of diameter 20 cm will be (Surface tension for soap solution is 30 dynes/cm )

The excess pressure inside a soap bubble of diameter 2 cm of soap solution of surface tension

The excess of pressure in a soap bubble of diameter 10 mm , when the surface tension is 0.04N//m is
