Calculation of Surface Energy of Soap Bubble

Given data:
Surface tension (๐œŽ) = 30 x 10^-2 N/m
Radius of soap bubble (r) = 5 cm = 0.05 m

Formula used:
Surface energy (E) = 4๐œ‹r^2๐œŽ

Calculation:
Surface energy (E) = 4๐œ‹r^2๐œŽ
= 4 x 3.14 x (0.05)^2 x 30 x 10^-2
= 1.8 x 10^-2 J

Therefore, the surface energy of soap bubble is 1.8 x 10^-2 J, which is the correct option (D).
