Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 7.1.1, have higher viscosities. Water, gasoline, and other liquids that flow freely have a low viscosity. For some of the terms, you may need to consult sources other than your textbook, such as a dictionary or encyclopedia. The McGraw-Hill Dictionary of Chemistry provides a compendium of 8000 terms that are central to chemistry and related fields of science and technology. Viscosity is the result of frictional interactions within a given liquid and is commonly expressed in two different ways. The viscosity of a liquid is a measure of its resistance to flow. If the liquid molecules are strongly attracted to the tube molecules, the liquid creeps up the inside of the tube until the weight of the liquid and the adhesive forces are in balance. Viscosity There are two basic types of flow, these being shear flow and extensional flow.In shear flow fluid components shear past one another while in extensional flowfluid component flowing away or towards from one other.
