I THINK IT GETS DIVIDED INTO MANY SMALL SPHERES...INSTEAD OF A LARGE SPHERE..
THERE ARE NOT SO GREAT INTERMOLECULAR FORCES BETWEEN THE WATER MOLECULES..WHICH CAN HOLD THEM TOGETHER,,
NOW SEE THE SMALLER DROPS...THEY HAVE CONSIDERABLY SMALL ENERGY THAN THAN A BIG ONE DROP...THOSE DROPS ARE MORE STABLE ..SO THEY ARE FORMED

YA IT WILL BE GREATER TAKEN TOGETHER..i accept<<<
BUT I AM TELLING THE SMALLER SPHERES INDIVIDUALLY...TAKE ONLY ONE SPHERE AT A TIME...
SO ON THE NET ENERU INCREASES,.,BUT IT HAS DIVIDED INTO MANY SMALLERE SPHERES NOW...AND EACH SPHERE IS MORE STABLE

There are two points that i would like to consider
1. If energy is pumped in to a system, the tendency of the system to fall back to the minimum energy can not expected to be manifested. For example if you cick a ball it goes up increasing its potential energy. That is, as the water drop splits up its net surface potential energy increases. But each of the smaller droplets formed is much more stable than the big one.
2.A water drop as it falls down experiences a lot of viscous drag which distorts its shape out of sphere and causes it to break apart.But once it has broken in to sufficiently smaller droplets they may retain their spherical shape more or less.

Wasn't there something about entropy?
It is one of the factors which determines whether a process will be manifested or not
It says that the natural tendency of a body is to spread, to delocalize.
eg. Two different gaseous compounds when mixed have a tendency of intermixing thoroughly.
Also, as pointed out above, since energy acts upon the system, the system rearranges itself so as to minimize the effect of the energy change to remain.
When a solid is heated, energy flows into it. As a result, it turns into a liquid. True, its energy levels are raised. But, its molecules move apart to minimize the affect of this new energy (this reduces the intermolecular forces)

by doing this it increases its surface area causing increase in its potential energy as work is done against force of intermolecular attraction
but the natural tendency of body is to have minimum potential
please explain me about this doubt
