capillary rise is due to adhesive forces between the walls of the capillary tube and the fluid. adhesive forces pull the edges of the fluid upwards. the surface tension in the fluid constantly pulls molecules from the surface inward (due to higher molecular energy levels at the surface), but also holds the molecules at the surface together (cohesive forces). this causes all of the fluid to rise rather than just the fluid at the edges. the surface tension is fighting against the adhesive forces as well as the forces due to the weight of the fluid column being lifted. at a certain point, the weight of the fluid column being lifted will cause a net force greater than what the surface tension forces can withstand, and the fluid will stop rising. I suppose a change in the adhesive forces could cause a change in the capillary action (maybe a coating of something on the surface of the capillary tube, like a surfactant). the temperature of the fluid would also change things due to the higher energy levels of the molecules in the fluid and lowered attraction between them.
randomly thought id answer this since im answering nearly an identical question on a lab report right now.
What else can I help you with?
What is the attraction between molecules that result in the rise of liquid in small tubes?
capillarity, also known as capillary action.
Oil flows upward in the wick of a lantern because of the liquid property called A viscosity B capillarity C meniscusity D density?
B. Capillarity. Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of external forces, such as gravity. This property explains why oil moves upward in a wick against the force of gravity.
What happens to water molecules to cause adhesion to occur?
You think probable to capillarity.
What are the factors that affect experemnt?
variables
What factors affect colloids?
Factors that affect colloids include particle size, particle charge, temperature, and presence of electrolytes. These factors influence the stability and behavior of colloidal systems.
What is the significance of capillarity in fluid flow problems?
Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. In fluid flow problems, capillarity plays a role in phenomena like rise or fall of liquid in small tubes, contact angle between liquid and solid surfaces, and wettability. These effects can affect the behavior of fluids in porous media, microfluidic devices, and biological systems.
What is the attraction between molecules that result in the rise of liquid in small tubes?
capillarity, also known as capillary action.
How does particle size effect capillarity?
As long as the spaces between the particles are connected, the smaller the particles, the higher the capillarity. The larger the particles, the lower the capillarity.Particle size and capillarity are inversely, or negatively related.
What organism uses capillarity?
a plant
What factors account for different capillarity in soils?
Texture, for one. Coarser soils (sandy) have much less capillary action than finer soils (clayey).

What are the examples of capillarity?
Examples of capillarity include the ability of water to rise in a narrow glass tube (capillary action), the spread of ink on paper through capillary action, and the movement of water through the roots and stems of plants.
