Playing with Drops - 1

A number of mercury drops at room temperature are made to combine acrobatically to form a big single drop.

What can you say about the temperature of this big drop thus formed?

The summation of surface energy (arising due to surface tenson ) of the individual mercury drops is greater than the surface energy of the bigger drop.The loss in energy goes into the heating of mercury drop. I would be happy if any one correct me if I am wrong .

You have a valid point
