Question

Accepted Answer

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

Capillary action occurs due to the combination of adhesive forces between the liquid and the surface it is in contact with, and cohesive forces between the liquid molecules.
Surface tension is the tendency of a liquid surface to minimize its surface area, caused by the cohesive forces between the liquid molecules.
Wetting is the ability of a liquid to spread over a surface, while non-wetting is the inability of a liquid to spread over a surface.
Water wets glass, while mercury does not.
Viscosity is the measure of a fluid's resistance to flow.
Honey has a higher viscosity than water.
