Question

The rise of water in a glass capillary will be minimum at ?

Answer 1

Answer:

Rise will be min. at the poles

Explanation:

Answer 2

The rise of water in a glass capillary will be minimum when the diameter of glass tube is smallest.

• Definition: Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
• The thinner the space in which the water can travel, the higher it goes up i.e. inversely proportional.
• In air, if water is used as standard fluid in standard conditions, then the  capillary length will be 2.71 mm.
• As the pore size get smaller, the value of the permeability is lower,and the capillary pressure will be higher
