Two mercury drops (each of radius \(r\)) merge to form a bigger drop. The surface energy of the bigger drop, if \(T\) is the surface tension, is

Work \(W\) is required to form a bubble of volume \(V\) from a given solution. What amount of work is required to be done to form a bubble of volume \(2 V\) ?

The surface tension of a soap solution is \('T'\). The work done in blowing a soap bubble of diameter \('d'\) to that of a diameter \('2\,d'\) is
1 \(6 \pi d^{2} T\)
2 \(4 \pi d^{2} T\)
3 \(2 \pi d^{2} T\)
4 \(8 \pi d^{2} T\)
Explanation:
The amount of work done to blow a bubble is the change in surface energy of the bubble. Now, \(\Delta W=2 T \cdot d A\) \(\Delta W=8 \pi T\left[d^{2}-\dfrac{d^{2}}{4}\right]=8 \pi T \times \dfrac{3 d^{2}}{4}=6 \pi d^{2} T\)
