Question

The surface tension of a particular liquid is 0.052 N/m. Several spherical bubbles of this liquid are floating through the room. One of the bubbles has a diameter of 1.2 cm and another has a diameter of 0.8 cm. Assuming the air in the room is at standard atmospheric pressure, find the absolute pressure in both bubbles. The two bubbles connect and become one. Is this process best pictured as (a) the smaller bubble getting bigger and the larger getting smaller, (b) the smaller bubble getting shrinking and the larger bubble growing, or (c) something else entirely? If (c), what is that ”something else”? No matter what your answer is, justify it with good physical reasoning.

Thanks for asking.
