What is the excess pressure inside a soap bubble? derive expression... ❤❤❤​

Answer 1

Answer:

Hi buddy

Explanation:

Consider a soap bubble of radius R and surface tension T. There are two free surfaces of soap bubble. Due to surface tension, the molecules on the surface film experience the net force in the inward direction normal to the surface. Therefore, there is more pressure inside than outside.
