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.

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.


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.


When the block was placed in the liquid why did the liquid rise?

The matter of the block displaced the water causing the water to rise


Which would most likely cause the liquid in Tube A to rise?

If the liquid in Tube A is connected to a vacuum pump and the pressure in the system is decreased, the liquid in Tube A will rise due to the reduced pressure in the tube allowing the liquid to travel upwards.


What we called the tendency of liquid molecules to rise spontaneously up tubes with narrow diameters?

That is capillary attraction.


Why does liquid rise higher when an object placed in it?

The liquid rises higher when a object is placed inside of it is because the mass of the object takes up space inside the liquid, which pushes the liquid in a direction that has space available.


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.


As water is heated it expands and becomes?

less dense, causing it to rise. This is because the heat causes the water molecules to move apart, increasing the volume they occupy. This decrease in density and increase in volume is what causes the hot water to rise.


Which instrument makes use of the fact that most liquids expand when they are heated?

A thermometer utilizes the fact that most liquids expand when heated. As the temperature of the liquid inside the thermometer increases, its volume expands, causing the liquid to rise within the narrow tube of the thermometer and indicating a higher temperature reading.


Why does water vapor rise when liquid water is heated by the sun?

By heating the intermolecular forces are weakened and liquid molecules can escape as a gas.


How does a liquid thermometer works?

A liquid thermometer works based on the principle of thermal expansion. As the temperature increases, the liquid inside the thermometer expands and rises in the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the liquid contracts and falls, showing a lower temperature.


What is the phenomenon of capillarity?

Capillary action, or capillarity, is a phenomenon where liquid spontaneously rises in a narrow space such as a thin tube, or in porous materials. This effect can cause liquids to flow against the force of gravity. It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces; If the diameter of the tube is sufficiently small, then the combination of surface tension and forces of adhesion between the liquid and container act to lift the liquid
