Explain why Surface tension of a liquid is independent of the area of the surface


What is the excess pressure inside a bubble of soap solution of radius 5.00 mm, given that the surface tension of soap solution at the temperature (20 °C) is 2.50 × 10–2 N m–1?

(1 atmospheric pressure is 1.01 × 105 Pa).
