 was pressure may balance the resultant force side oyer that on the convex side, so that the forces of Excess of pressure inside the drop, . Dut to excess of pressure, let there be increase in the radius of the drop yo sndell quantity , Fig. . then, work done by the excess pressure force displacement (excess pressure area) increase in radius lecrease in surface area of the drop final surface area - initial surface area [Neglecting, being very very small] :. Inerease in potential energy increase in surface area surface tension As the drop is in equilibrium, the increase in potential energy is at the cost of work done by the excess psiare, therefore from (11) and (12), we get 1030. EXCESS PRESSURE INSIDE A SOAP BUBBLE Consider saap bubble of radius . The molecules, lying on the surface of liquid bubble will experience issilan force acting inwards perpendicular to the surface due to surface tension. Since the size of soap wht cannot be reduced to zero, therefore, the pressure inside the soap bubble must be greater than the trweccutside it. This excess of pressure inside the bubble will provide a force acting outwards perpendicular Dte urface of bubble to counter balance the resultant force due to surface tension and the bubble is in Guitrion. La, surface tension of the soap solution, atmospheric pressure, total pressure inside the soap bubble Evcess of pressure inside the soap bubble, . Due to it, let there be increase in the radius of the bubble by a small amount 4. 18. 10.24. Then, work done by the excess pressure force distance (excess pressure area) increase in radius The wap Whitiasile the bubble has two free surfaces, one outside the bubble and the aside the bubble where soap solution and air are in contact.
