What is free surface energy ?

What is free fall?

What is surface energy? Establish the relation between surface tension and surface energy.

A big water drop is formed by the combination of 'n' small water drops of equal radii. The ratio of the surface energy of 'n' drops to the surface energy of big drop is

The surface energy of a liquid drop is u . If it is split into 1000 equal droplets , then its surface energy becomes .

The surface-tension of a liquid is T. The increase in its surface energy on increasing the surface area by A is........

If a million tiny droplets of water of the same radius coalesce into one larger drop, the ration of the surface energy of the large drop to the total surface energy of all the droplets will be
