CapillaryHardQuestion 22122
Question
Capillary rise is inversely proportional to tube radius because a narrower tube:
- AAllows the surface-tension effect to lift liquid higherCorrect
- BDecreases adhesive force to zero
- CRemoves gravity
- DMakes density vanish
Correct answer
Allows the surface-tension effect to lift liquid higher
Explanation
The same upward force acts over a smaller cross-section.
