The excess pressure inside a soap bubble P and the radius R of the bubble are related as
A soap bubble of radius 6 cm and another bubble of 8 cm coalesce under isothermal xonditions in vacuum. The radius of the new bubble is
The surface area of a spherical bubble is increasing at the rate of 2cm^(2)/s. When the radius of the bubble is 6cm at what rate is the volume of the bubble increasing?
Two soap bubbles of radii 2 cm and 4 cm join to form a double bubble in air, then radius of. curvature of interface is
A and B are two soap bubbles. Bubble A is larger than B. If these are now joined by a tube then
