Viscosity 1. (1) When you pour yourself a glass of milk, you are making use of a familiar physical property of liquids. (2) Because particles in a liquid are free to move around one another, a liquid can flow from place to place. (3) The physical property of liquids called viscosity is the resistance of a liquid to flowing. (4) Because liquids differ in viscosity, some liquids flow more easily than others. 2. The greater the viscosity of a liquid, the slower it flows. For example, molasses is a thick, sticky liquid with high viscosity. Molasses flows slowly. The lower the viscosity, the more easily a liquid flows. Water, rubbing alcohol, and vinegar are thin, runny liquids that have relatively low viscosities.In which sentence is the topic of this passage first mentioned
