Which term describes a fluid's resistance to flow?

Explanation:
A fluid's resistance to flow is described by viscosity. Viscosity is the internal friction that resists shear, so thicker fluids with high viscosity flow more slowly, while low-viscosity fluids like water flow easily. Temperature can affect viscosity (typically higher temperature lowers viscosity), whereas density and volume describe how much matter is present or how much space the fluid occupies, not how readily it moves.
