metals).

Capillary Action

Spontaneous rising of a liquid in a narrow tube.

Illustration of capillary action for large and small bore capillaries, and for positive and negative contact angles.

ViscosityLiquids are fluids – they FLOW.

Viscosity is the resistance to flow.

High viscosity is an indication of strong

intermolecular forces

Glycerine, also called glycerol, is a liquid with a high viscosity
