Final answer:
Viscosity is a measure of a liquid's resistance to flow. Factors such as intermolecular forces, molecule size and shape, and temperature affect viscosity. Liquids with high viscosity flow more slowly and stick to surfaces.
Step-by-step explanation:
The viscosity of a liquid is a measure of its resistance to flow. Liquids with low viscosity, such as water, flow easily, while liquids with high viscosity, such as syrup, flow more slowly and stick to surfaces. Viscosity is affected by several factors including the intermolecular forces (IMFs) between the molecules of the liquid, the size and shape of the molecules, and the temperature.
