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.

hope this helps :)

The fource which causes liquid to rise in a narrow tube is?
surface tensions
What is your understanding of effects of pressure changes on the boiling point of a liquid?
The effects of changing pressure on the boiling point of a liquid is that the water becomes temperature becomes higher. The boiling point will continue to rise depending on the amount of pressure applied.
Which would most likely cause the liquid in Tube A to rise?
water passing from a region of lower starch concentration to one of higher starch concentration
Can a liquid dissolve a gas?
There are a number of ways in which a gas could dissolve in a liquid. It could bind with the liquid molecules.
How to change water vapor back to liquid?
If the water vapour comes in contact with a surface and is allowed to cool and condense, it will turn back to liquid. For example, if you were to boil a pot of water with a lid on top, the water vapour would rise, touch the underside of the pot lid and condense to form droplets (liquid).
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 fource which causes liquid to rise in a narrow tube is?
surface tensions
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
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.
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.
What is your understanding of effects of pressure changes on the boiling point of a liquid?
The effects of changing pressure on the boiling point of a liquid is that the water becomes temperature becomes higher. The boiling point will continue to rise depending on the amount of pressure applied.
What might happen if enough energy is absorbed by liquid water?
The temperature will rise, and the water will evaporate.
Which would most likely cause the liquid in Tube A to rise?
water passing from a region of lower starch concentration to one of higher starch concentration
Why does steam rise in a pond?
The water temperature is higher then the surrounding air.
What is a scientific term for the ability of water molecules to rise up a very narrow tube?
That's called - 'capillary action'.
