Capillarity with a too-short tube: What happens to the water rise? If a thin capillary tube is replaced by another tube of insufficient length compared with the predicted capillary rise, predict the observed behavior. Choose the correct option.

Q: Capillarity with a too-short tube: What happens to the water rise? If a thin capillary tube is replaced by another tube of insufficient length compared with the predicted capillary rise, predict the observed behavior. Choose the correct option.

Concept Capillary rise height h is set by surface tension, density, gravity, and radius. If tube length < theoretical rise, the liquid simply reaches the open end and overflows. Final Answer Water rises to the top and overflows (spills)

Difficulty: Easy

Water rises to the top and overflows (spills)
Water does not rise at all
Angle of contact becomes zero so rise is infinite
Meniscus inverts to convex

Correct Answer: Water rises to the top and overflows (spills)

Explanation:

Concept

Capillary rise height h is set by surface tension, density, gravity, and radius.
If tube length < theoretical rise, the liquid simply reaches the open end and overflows.

Final Answer
Water rises to the top and overflows (spills)
