Answer:
4) Resistance
Step-by-step explanation:
Viscosity is a property that describes how resistant a substance is to flow. It determines how easily or difficultly a liquid can flow or move. When a liquid has high viscosity, it means it is thick and flows slowly, like honey or syrup. On the other hand, liquids with low viscosity are thin and flow easily, like water or oil. So, viscosity can be thought of as the measure of a liquid's resistance to flow.
