Radius of a soap bubble is increased from R to 2 R work done in this process in terms of surface tension is

The radius of a soap bubble is increased from (1)/(sqrtpi) cm to (2)/(sqrtpi) cm. If the surface tension of water is 30dynes per cm, then the work done will be

The gas inside a spherical bubble expands uniformly and slowly so that its radius increases from R to 2R . Let the atmospheric pressure be p_(0) and surface tension be S . The work done by the gas in the process is

Calculate the work done in increasing the radius of a soap bubble in air from 2 cm to 3 cm. The surface tension of the soap solution is 27 dyn/cm.

Calculate the work done in increasing the radius of a soap bubble in air from 2 cm to 3 cm. The surface tension of soap solution is 25 dyne/cm.

A soap bubble has a radius of 6cm. The work done in increasing the radius from 6 cm to 10 on will be (in mJ). (Surface tension of soap solution is 0.04 Nm.)

Air is pushed into a soap bubble of radius r to double its radius, of the surface tension of the soap solution is S, the work done in process is
