derive an expression for the rise of liquid in a capillary tube
It is our common observation that the liquid always rises in a capillary tube , the effect is referred to as the " CAPILLARY ACTION ".capillary action of liquid is also due to their surface tension. the surface area to volume ration of a capillary of small bore is much smaller than the container in which liquid is placed. Like viscosity , the surface tension of a liquid also decreases with the rise of temperature owing to the weakening of the inter molecular attractions .
The 'capillary effect'. See the link.
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.
The tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension.
That is capillary attraction.
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.
capillarity, also known as capillary action.
Capillary tubes are renowned for their capillary action on liquids, i.e. they cause liquids to rise up inside them. Capillary tubes are the essence of thermometers that use a liquid indicator. In biology and the plant world, capillary tubes are fundamental to the movement of fluids through the systems of living organisms.
the air in the liquid is blocked off by your mouth when its on the straw so when u sip the flow of air and carbons bring the liquid thorugh the straw through capillary action http://www.answers.com/topic/capillary-action-1
