Question

Two water droplets combine to from a large drop in this process energy is

Answer 1

When two water droplets combine to form a large and single drop its combination decreases the surface area as

surface area of two droplet will be larger than single droplet and thus reducing the surface tension.As surface tension reduces its energy also reduces thus releasing energy.

So we can say that when two water droplet combine together to form a single droplet it releases energy.
