Capillary Length Rise Tube

AI Thread Summary

Capillary rise in a tube of insufficient length does not result in overflow because the adhesive forces between the liquid and the tube's walls are balanced by cohesive forces within the liquid. This balance prevents the liquid from rising indefinitely. The phenomenon is primarily driven by capillary action, which is the result of these attractive forces. The interplay of adhesive and cohesive forces determines the height to which the liquid can rise without spilling over. Understanding these forces is essential for comprehending capillary action in various applications.

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?

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
