A soap bubble assumes a spherical surface . Which one of the following statement is wrong ?

Options

A. The soap bubble encloses air inside it
B. The soap film consists of two surface layers of molecules back to back
C. The pressure of air inside the bubble is less than the atmospheric pressure.hence the atmospheric pressure compresses it equally from all sides to give it a spherical shape.
D. Because of the elastic property of the film , it tends to shrink to as small a surface area as possible for the volume it has enclosed .

Answer

C

Explanation

The pressure inside the soap bubble is more than the atmospheric pressure - excess pressure =`(4T)/R`
Hence (c ) is the wrong option .
