When ‘n’ identical droplets are combined to form a big drop, then the energy will be released If n identical small droplets each of radius r merge to form a big drop of radius R and the energy released in this process is absorbed by the big drop so as to increase its kinetic energy then the speed of the big drop (T be the surface tension and d be the density of the liquid droplets)

When ‘n’ identical droplets are combined to form a big drop, then the energy will be released If n identical small droplets each of radius r merge to form a big drop of radius R and the energy released in this process is absorbed by the big drop then rise in temperature (T be the surface tension, d be the density and S be the specific heat of the liquid droplets)
