Capillary rise in tube of insufficient length

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of capillary rise in a tube that is insufficiently long to allow for overflow. Participants explore the mechanisms behind capillary action and the forces involved.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions why liquid does not overflow in a tube of insufficient length during capillary rise.
  • Another participant states that capillary action is attractive and describes it as pulling water into a tube.
  • A subsequent post reiterates the attraction of capillary action and inquires whether this attraction is due to adhesive and cohesive forces.
  • A later reply confirms the inquiry by referencing an external source on capillary action.

Areas of Agreement / Disagreement

Participants express similar views on the nature of capillary action, but the initial question regarding the lack of overflow remains unresolved, with no consensus on the underlying reasons.

Contextual Notes

The discussion does not address specific assumptions about the properties of the liquid or the tube, nor does it clarify the definitions of adhesive and cohesive forces in this context.

When there is Capillary rise in tube of insufficient length, why does not the liquid overflow?

Capillary action is attractive: it pulls water into a tube.

Is this attraction due to adhesive - cohesive forces?
