Work Done in Blowing a Bubble!

Classical Mechanics Level 3

A spherical soap bubble of radius R R is blown from a tiny drop of soap solution. If the surface tension of the soap film is T T , the work required to make the bubble is

4 π R 2 T 4 \pi R^2 T 8 π R 2 T 8 \pi R^2 T 6 π R 2 T 6 \pi R^2 T 2 π R 2 T 2 \pi R^2 T

Total surface energy = T ∗ A r e a = 2 T ∗ 4 π R 2 = 8 π R 2 T T*Area = 2T*4 \pi R^2 = 8 \pi R^2 T
