🇬🇧🇪🇸 viscosity - viscosidad : English Lesson

Meaning of "viscosity" ("viscosidad"), detailed definition, and a short video lesson below.

Viscosity is a way to describe how easily a liquid flows. A liquid with low viscosity, like water or juice, flows and pours very quickly. A liquid with high viscosity, like honey or slime, is thick and slow and doesn’t want to move. Scientists measure viscosity to compare how runny or gooey different liquids are, kind of like giving each liquid a “speed score” for how fast it can flow.
