Question

What phenomenon describes the motion of liquid in a tube?

Answer 1

Capillary action describes the motion of liquid in a tube

What is capillary action?

• When a liquid flows in any narrow space like a tube or something, it flows against gravity without the influence of any external force. This phenomenon is called capillary action.

Why capillary action occurs?

• When the force of cohesion between the walls and the liquid is stronger than the force of attraction between the molecules of the liquid, then the cohesive forces take over and the liquid starts moving up the tube.

• The height liquid reaches, obviously depends upon the force of gravity and the surface tension.

Final Answer

Capillary action is the phenomenon that describes the motion of liquid in a tube.
