JEE Main2004PhysicsMechanical Properties of FluidsActual
If two soap bubbles of different radii are connected by a tube,
Options
- Aair flows from the bigger bubble to the smaller bubble till the sizes are interchanged.
- Bair flows from bigger bubble to the smaller bubble till the sizes are interchanged
- Cair flows from the smaller bubble to the bigger.
- Dthere is no flow of air.
Correct answer
C. air flows from the smaller bubble to the bigger.
Step-by-step solution
The pressure inside the smaller bubble will be more (P_i=P₀+ 4 T r ) Therefore, if the bubbles are connected by a tube, the air will flow from smaller bubble to the bigger.
