A soap bubble of radius R has formed at normal temperature and pressure under isothermal conditions. Complete the work done. The surface tension of soap solution is `T`.

A soap bubble of radius r is blown up to form a bubble of radius 2r under isothermal conditions . If T is the surface tension of soap solution , the energy spent in blowing

A soap bubble of radius r si blown up to form of bubble of radius 3r under isothermal conditions . What is the energy spent in doing so if the surface tension of soap solution is S.

A soap bubble of radius 'r' is blown up to form a bubble of radius 2r under isothemal conditions. If sigma be the surface tension of soap solution , the energy spent in doing so is

A soap bubble of radius 'r' is blown up to form a bubble of radius 2r under isothemal conditions. If sigma be the surface tension of soap solution , the energy spent in doing so is

A soap bubble of radius 'r' is blown up to form a bubble of radius 2r under isothemal conditions. If sigma be the surface tension of soap solution , the energy spent in doing so 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.
