The fource which causes liquid to rise in a narrow tube is?
The force that causes liquids to rise in a narrow tube is called capillary action. This phenomenon occurs due to the combination of adhesive forces between the liquid and the tube walls and cohesive forces within the liquid itself. Capillary action is more pronounced in narrower tubes due to the increased surface area for interaction between the liquid and the walls.
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.
How would you use capillary in a sentence?
The liquid was pulled into the small tube by capillary action.
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.
Can stalagmometer used for viscosity measure?
No, a stalagmometer is not used for viscosity measurement. It is used to determine the surface tension of a liquid by measuring the time taken for a drop to fall through a capillary tube. Viscosity is typically measured using viscometers or rheometers.
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.
How capillary rise and diameter depends?
Capillary rise is influenced by the diameter of the capillary tube; specifically, narrower tubes exhibit a greater height of liquid rise due to stronger adhesive forces between the liquid and the tube walls relative to the cohesive forces within the liquid. This phenomenon is described by the capillary action equation, where the height of rise is inversely proportional to the diameter of the tube—smaller diameters lead to higher capillary rise. As the diameter increases, the height of the liquid column decreases, demonstrating the strong relationship between tube size and capillary action.
Why does liquid rise in a capillary tube?
Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.
What is the name of the phenomenon in which thin liquids in thin tubes rise above or fall beneath their own levels?
The phenomenon is known as capillary action. It occurs due to intermolecular forces between the liquid molecules and the solid surface of the tube, causing the liquid to either rise or fall, depending on the properties of the liquid and the tube.
What is the tendency of a liquid to rise in a small diameter tube called?
The 'capillary effect'. See the link.
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.
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
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.
The fource which causes liquid to rise in a narrow tube is?
The force that causes liquids to rise in a narrow tube is called capillary action. This phenomenon occurs due to the combination of adhesive forces between the liquid and the tube walls and cohesive forces within the liquid itself. Capillary action is more pronounced in narrower tubes due to the increased surface area for interaction between the liquid and the walls.
How determine the surface tension of liquid using capillary rise method?
The surface tension of a liquid can be determined using the capillary rise method by measuring the height to which the liquid rises in a capillary tube. According to the formula ( \gamma = \frac{h \cdot \rho \cdot g \cdot r}{2} ), where ( \gamma ) is the surface tension, ( h ) is the height of the liquid column, ( \rho ) is the density of the liquid, ( g ) is the acceleration due to gravity, and ( r ) is the radius of the capillary tube. By accurately measuring these parameters, the surface tension can be calculated. This method relies on the balance between the adhesive forces between the liquid and the tube and the cohesive forces within the liquid.
