1.	Let n number of little droplets of water of surface tension S dyn. Cm^-1, all of the same radius r cm, combine to form a single drop of radius R cm. J is joule's mechanical equivalent of heat. While using CGS system of units answer the following questions. iii. What is the change in excess of pressure inside the big drop formed and a small drop if the change in temperature is ignored ?
