excess pressure inside a liquid drop/soap bubble/class 11 physics/iit jee fluid mechanics

Due to excess pressure inside the liquid drop the free surface of the drop will experience the net force in outward direction due to which the drop will expand. ... Therefore excess of pressure does the work in displacing the surface and that work will be stored in the form of potential energy.
