State
Viscosity is a liquid's resistance to flow, set by its intermolecular force strength and its molecules' size and shape.
Show
Honey, with strong attractions between its large sugar molecules, flows far more slowly than water.
Watch for
Treating viscosity as a fixed property of a liquid ignores that raising temperature lowers it, since faster molecules more easily overcome the same intermolecular forces.
Unlocks
- Nothing yet depends on this.
