Question

. 1000 droplets of water having 2mm diameter each coalesce to form a single drop. Given the surface tension of water is 0.072 Nm­1. The energy loss in the process is

Answer 1

The correct answer is: 1.5825 x 10^-5 J/m2.

Energy is the qualitative property which works on being transferred from one object of the subject to another object of the subject. In the process of transferring of energy since the efficiency of machines is not absolute or 1 in most of the cases except the ideal cases so energy is lost in the process of transferring of one body to the another body. Hence energy is lost in this case also.
