Question

Two spherical soap bubbles coalece. If V is the consequent change in volume of the contained air and S is the change in the total surface area and T is the surface tension of the soap solution then
(if $P_{0}$ is atmospheric pressure)
[Assume the temperature of the air remain same in all the bubbles]

3 P_{0} V + 4 S T = 0
