A soap bubble has radius R and surface tension S , How much energy is required to double the radius with out change of temperature .

The work done in blowing a soap bubble of radius r of the solution of surface tension T will be

One large soap bubble of diameter D breaksinto 27 bubbles having surface tension T. The change in surface energy is

Under isothermal condition, energy E is supplied to a soap bubble of surface tension sigma and radius r, to double the radius of the soap bubble. The value of E is

A soap bubble of diameter 6mm is formed in air . The surface tension of liquid is 30 dyne/cm . The excess pressure inside the soap bubble is

A bubble of 8 mm diameter is formed in the air. The surface tension of soap solution is 30 dynes/cm . The excess pressure inside the bubble is

The surface tension of soap solution is 0.035 N/m . The energy needed to increase the radius of the bubble from 4 cm to 6 cm is

Two identical soap bubbles each of radius r and of the same surface tension T combine to form a new soap bubble of radius R . The two bubbles contain air at the same temperature. If the atmospheric pressure is p_(0) then find the surface tension T of the soap solution in terms of p_(0) , r and R . Assume process is isothermal.

A soap bubble of radius R is blown. After heating the solution a second bubble of radius 2 R is blown. The work required to blow the second bubble in comparison to that required for the first bubble is
