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.
capillarity, also known as capillary action.
the two factors that affect philippine climate are it's location and the equator
Capillarity. Capillarity is the upward movement of water from roots to leaves, through xylem. Transpiration is the evaporation of water from the leaves through stomates.
Three factors that affect air pressure are temperature, altitude, and water vapor.

As particle size in increases, capillarity decreases
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.
Texture, for one. Coarser soils (sandy) have much less capillary action than finer soils (clayey).

a plant
Capillarity is the movement of liquid without any external forces. The flow of oil in a wick absorption of liquid by paper towel are examples of capillarity.
