The more narrow the tube, the greater the rise of the liquid. … However, increased density of the liquid will cause it to rise to a lesser degree. The force with which water is held by capillary action varies with the quantity of water being held.

What factors influence capillary action?

Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).

How do you increase capillary action?

Increase capillary action: Increase temperature, decrease capillary tube diameter, perform any number of actions to decrease surface tension, etc…! Decrease capillary action: The opposite of the steps you would take to increase, also, increasing the density of the liquid you’re working with.
