Web7 apr. 2024 · And work done in blowing bubble is given by, Δ w = T. d A We know that bubbles have two surfaces, one is inner and other one is outer. Therefore our work down is given by, Δ w = 2 T. d A Since our diameter is from D to 2D, therefore our area dA will also change. Δ w = 2 T [ 4 π ( 2 D 2) 2 − 4 π ( D 2) 2] By solving, Δ w = 2 T ( 4 π 3 D 2 4) WebGiven, the work done in blowing a bubble against surface tensional forces of volume V is W.
