Air is pushed inot a soap bubble of radius r to duble its radius. If the surface tension of the soap solution is S, the work done in the process is

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

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

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.

The excess pressure inside a soap bubble of radius R is (S is the surface tension)

The work done in blowing a soap bubble of radius 0.2 m is (the surface tension of soap solution being 0.06 N/m )

The work done in blowing a soap bubble of 10 cm radius is (Surface tension of the soap solution is 3/100 N/m)
