WebFor a single spherical surface balance is achieved if P i - P o = 2γ/r. This is known as Laplace's law for a spherical membrane. For a soap bubble with two surfaces P i - P o = 4γ/r. Problem: Calculate the gauge pressure inside a soap bubble 2 cm in radius using the surface tension for soapy water γ = 0.025 N/m. Solution: Reasoning:
