If sap bubbles of different radii are in communication with each other (a) Air flow from the larger bubble into the smaller one until the two bubbles are of equal size (b) The sizes of the bubbles remain unchanged. (c) Air flows from the smaller into the larger on and lager bubble grows at the expense of the smaller one (d) Air flows from the larger into the smaller one becomes equal to that of the larger one and the large one equal to that of the smaller one.

When two bubbles come into contact. They try to minimize the surface area for which air flows from bubble having higher pressure (smaller radius) to bubble having lower pressure.
