Find the work done in blowing a soap bubble

WebWork is Force times distance. So its pretty obvious that the work done in expanding a soap bubble is equal to the surface tension by the area, because this gives the right units: E = N * m = N/m * m^2 E = 0.06 N/m * xm^2 Where x is the change in surface area. WebMay 31, 2024 · If S is the surface tension of soap solution, then excess of pressure inside the soap bubble of radius `R_(1)` is `p_(1) = (4S)/(R_1)` Excess of pressure inside the soap bubble of radius `R_(2)` is `p_(2) = (4S)/(R_2)` (p_1)/(p_2) = (R_2)/(R_1) = 3/2` Work done in blowing up the soap bubble is `W = S xx` surface area of bubble
