What phrase best defines viscosities?

Explanation:
Viscosity is a measure of how much a liquid resists flowing, due to internal friction between its layers. A high-viscosity liquid, like honey, resists flow more and moves slowly; a low-viscosity liquid, like water, flows readily. So the phrase that defines viscosities is the liquids’ resistance to flow. Color, density, and boiling point describe other properties—appearance, mass per volume, and the temperature at which a liquid boils—not how easily the liquid flows. Temperature can influence viscosity, typically lowering it as liquids heat up.
