How to Practise Surface Tension and Surface Energy
Learn the excess pressure inside a drop and a soap bubble, the capillary rise formula h = 2T cosθ/(ρgr), and the energy released when small drops merge into a large one. Practise the splitting and coalescence questions, where volume is conserved.
Then attempt the statement-based questions and redo any you missed after a day.
