What else can I help you with?
What occur only on the surface of the substance?
Surface tension and surface adsorption occur only on the surface of a substance. Surface tension is the tendency of a liquid surface to shrink into the minimum surface area possible, while surface adsorption is the accumulation of molecules at the surface of a material.
What end of the capillary does filtration occur?
Arteriole
What types of bonds allow different water molecules to be attracted to one another and allows capillary action to occur?
These are hydrogen bonds between water molecules.
Where does the exchange of food and oxgyen and wastes occur?
capillary
What is the basic use of capillary tube?
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.
Where does surface tension occur?
surface layer molecules only have attractions downwards and sidewards no upwards attraction is there so the sidewards attraction will acts as a elastic force rusult to surface tension manoj kottakkal
What happens at a capillary?
exchage of materials between blood and tissues occur in cappilaries.
Do exchanges between blood and tissue cells occur in capillary beds?
yes
What part of the plot does little no action occur?
In the rising action of a story, there may be little action as the setting, characters, and conflicts are established. This part of the plot typically involves building tension and introducing the main problem or challenge that the characters will face.
What is the relationship between particle size and capillarity?
As the particle size decreases, capillarity increases. Smaller particles have more surface area for capillary action to occur, allowing liquids to be drawn up higher through the small spaces between particles. This relationship is important for understanding how liquids move through porous materials such as soil or rock.
Why does a meniscus occur?
A meniscus occurs due to the adhesive and cohesive forces between a liquid and a solid surface. The curvature of the meniscus is caused by the differing surface tensions at the interface of the liquid and solid.
Why is filter paper used in chromatography?
Filter paper is used in chromatography because it is porous and allows the solvent to travel through it by capillary action. This helps separate the components of a mixture based on their solubility and affinity for the stationary phase. The filter paper also provides a large surface area for the separation to occur effectively.
