The sum of the masses of the two droplets is equal to the original mass of the drop.

Vedclass · Answer

(B) When a drop of water breaks into two droplets,the total mass of the system remains conserved according to the law of conservation of mass.Let the radius of the original drop be $R$ and the radius of each of the two smaller droplets be $r$. Since the mass is conserved,the total volume remains constant:$\frac{4}{3} \pi R^3 = 2 	imes \frac{4}{3} \pi r^3$This simplifies to $R^3 = 2r^3$,or $R = 2^{1/3} r$.Since the total mass is the sum of the masses of the individual droplets,option $B$ is correct. The surface area increases during this process,and the temperature typically changes due to the change in surface energy.
