Ever wondered why a small liquid drop or soap bubble maintains its perfect spherical shape? The answer lies in Excess Pressure! In this comprehensive physics lesson, we dive deep into the fascinating phenomenon of excess pressure across a liquid drop and a soap bubble. We'll break down the fundamental concepts and show you the clear, step-by-step derivation of the pressure difference, also known as Laplace's Law of Spherical Membranes.

We start by explaining the role of surface tension ($\gamma$ or $T$) and how it creates an inward force on the surface of the liquid. You'll learn the crucial distinction: a liquid drop has only one free surface, while a soap bubble has two free surfaces (inner and outer), which doubles the excess pressure. We use the method of virtual displacement to calculate the work done and derive the final formulas:Excess Pressure in a Drop: $\Delta P = \frac{2\gamma}{R}$Excess Pressure in a Bubble: ΔP=R4γ​This video is perfect for high school (Class 11/12) and university students studying fluid mechanics and surface phenomena.
