PhysicsNEET 2022Surface tension, capillarity, excess pressure

Mechanical Properties of Fluids

If a soap bubble expands, the pressure inside the bubble:

A.Is equal to the atmospheric pressure
B.Decreases✓
C.Increases
D.Remains the same

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
