what causes a substance to display a greater capillarity?
Answers
Answer:
Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. ... Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.
Explanation:
Capillarity is the result of surface, or interfacial, forces. The rise of water in a thin tube inserted in water is caused by forces of attraction between the molecules of water and the glass walls and among the molecules of water themselves. ... The narrower the bore of the capillary tube, the higher the water rises.
The rise and fall of liquid in a capillary tube is called capillarity. Application is Oil rises in the long narrow spaces between the threads of the wick as they act as a capillary. Capillary rise is due to adhesion. An Example is water in a glass tube.
