Question

The length of a capillary tube is less than the height to which a liquid can rise in that capillary tube. Explain giving necessary expressions, what would happen in this case.​

Answer 1

Answer:

When length of tube is less than the height of capillary rise, the liquid molecules on reaching top of the capillary come into contact with horizontal surface of the tube. The surface tension becomes horizontal. There is no vertical force to pull the liquid up and it stops rising.
