It is because of the surface tension between liquid molecules and the inner surface of the tube. The meniscus height is determined by the inner diameter of the tube. The smaller the diameter, the higher the meniscus will climb due to capillary action.

How would you use capillary in a sentence?
The liquid was pulled into the small tube by capillary action.
Does liquid water rise higher in a narrow tube or a wide tube?
Rise or fall of liquid in a small passage or tube. When a glass tube of small internal diameter is inserted into water, the surface water molecules are attracted to the glass and the water level in the tube rises. The narrower the tube, the higher the water rises. The water is said to "wet" the tube. Water will also be drawn into the fibres of a towel, even if the towel is in a horizontal position. Conversely, if a glass tube is inserted into mercury, the level of the liquid in the tube falls. The mercury does not wet the tube. Capillarity is caused by the difference in attraction of the liquid molecules to each other and the attraction of the liquid molecules to those of the tube.
What is the capillary tube?
In chemistry... it's a thin open-ended glass tube for collecting small amounts of liquid. Inserting one end of the tube into liquid allows the liquid to flow upqwards. When the liquid reaches a suitable height, a finger placed over the open end (towards the top) holds the liquid in the tube - for transferring from one place to another.
The fource which causes liquid to rise in a narrow tube is?
surface tensions
Is mercury in any devices always in a capillary tube?
A thermometer has a capillary tube but a mercury switch in a heater thermostat has mercury that just rolls back and forth.
What is capilliarity?
The tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension.
Derive an expression for expression for rise of liquid in a capillary tube?
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
The rise of water in a narrow test tube is called?
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
What is the tendency of a liquid to rise in a small diameter tube called?
The 'capillary effect'. See the link.
Why there is capillary action and why the effect is greater for narrower tubes?
Liquid rises in and out of cappilarry to compansate pressure difference. Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.
Does liquid water rinse higher in a narrow tube or a wide tube?
You mean rise not rinse. Higher in a narrow tube due to capillary action.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
Why does mercury fall downwards and water rise upwards when placed in a capillary tube?
Mercury is more dense than water.
What is quincke 's method?
Quincke's method is a technique used to determine the surface tension of a liquid by measuring the maximum height to which the liquid rises in a capillary tube. It involves carefully introducing the liquid into the tube and allowing it to rise due to capillary action until it reaches equilibrium. The surface tension can then be calculated using the measured height and the properties of the liquid and the tube.
Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
Why is water rise in capillary tube wheras mercury falls in capillary tube?
i dont know ha ha ha
