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

A big drop of radius R is formed by coalescing 1000 small droplets of water. What will be the change in surface eneryg ? What will be the ratio between the total surface energy of the droplets and surface energy of the big drop ?

What is the surface energy of a soap bubble of radus r and surface tension T?

Surface charge density of soap bubble of radius r and surface tension T is sigma .If P is excess pressure the value of sigma is

A liquid drop having surface energy E is spread into 512 droplets of same size. The final surface energy of the droplets is

If r and T are radius and surface tension of a spherical soap bubble respectively then find the charge needed to double the radius of bubble.
