125 water droplets, each of radius r, coalesce to form a single drop. The energy released raises the temperature of the drop. If sigma represents surface tension,p represents density, S represents specific heat, then the rise in temperature of the drop is - ((eta +7) sigma)/(eta r p S) where eta is a dimensionless constant. Find eta .
