Question

excess pressure inside a soap bubble.​

Answer 1

Answer:

excess of pressure in a liquid drop or air bubble in a liquid is two times the surface tension of the liquid over the radius of the drop or yhe bubble. Whereas, in case of soap bubble that excess of pressure is equal to four times the surface tension over the radius.

The simple answer to "why is the pressure inside a soap bubble higher than outside," is that a higher pressure than the local atmosphere is required to make the bubble in the first place! This requirement comes from the need to counterbalance the surface tension force

Answer 2

Answer:

due to non polar tail and polar head.
