Two soap bubbles having radius in the ratio `1:2`. Compare the work done in blowing these bubbles.

The radius of an air bubble is increasing at the rate of (1)/(2) cm/s. At what rate is the volume of the bubble increasing when the radius is 1 cm?

Under isothermal conditionss, two soap bubbles of radii a and b coalesce to form a single bubble of radius c. If the external pressure is P, then surface tension of the bubbles is

The work down in blowing a soap bubble of volume V is W. The work is to be done in blowing it of volume 2V equals to

Two soap bubbles of radii x and y coalesce to constitute a bubble of radius z. Then z is equal to

The surface area of a spherical bubble is increasing at the rate of 2 cm^(2)//s . Then the rate at which the volume of the bubble is increasing at the instant when its radius is 6 cm, is-

Air is pushed into a soap bubble of radius R to triple its radius. If the surface tension of the soap solution is S, then find out an expression for the work done in this process.
