Question

give the derivation of excess of pressure inside a bubble in case of bubble.

Answer 1

ANSWER;
The balloon analogy can be used to understand this phenomena.

A flaccid balloon has zero tension on its surface, and the pressure inside it is same as the atmospheric pressure.

While inflating the balloon, you push air into it,thereby increasing the pressure inside it. This excess pressure aids in the inflation process. The balance between excess internal pressure and surface tension of the balloon’s membrane keeps it from collapsing/deflating.

Similar is the case with bubbles.
