What describes the thickness or flowability of a liquid at a given temperature?

Viscosity describes the thickness or flowability of a liquid at a given temperature. It is the liquid’s resistance to flow; a high viscosity means the liquid is thick and pours slowly (like honey), while a low viscosity means it pours easily (like water). At the same temperature, viscosity tells you how a chemical will spread, how easily it can be pumped, and how it behaves in containment or during transfer—essential factors in hazmat operations for predicting spread and selecting appropriate equipment and methods. Temperature influences viscosity: raising temperature typically lowers viscosity, making flow easier, while lowering temperature raises viscosity and slows flow. While density, boiling point, and odor are other important properties, they do not describe how thick a liquid is or how readily it flows.
