Chapter : Surface Tension : If a number of little droplets of liquid each of radius r coalesce to form a single drop of radius R, find the rise in temperature .......
Let n be the number of liquid droplets, each of radius r, coalesce, to form a single drop of radius R.
In this case area decrease, volume remains constant , surface energy decreases and temperature increases by
Δ θ = 3S/ρcJ . 1/r - 1/R
