![]() Pre-heating is of course an option, but the downside is higher energy. 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. Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly high viscosity fluids move sluggishly and resist deformation. Mineral oils for instance become more viscous, or thicker, at lower temperatures. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest. Measured values span several orders of magnitude. Viscosity is measured using a viscometer. For instance, honey has a much higher viscosity than water. ![]() On the other hand, if a fluid moves slowly, its viscosity is said to be high. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. For example, we say that honey is more viscous than water. ![]() Viscosity is a term we use to describe the 'thickness' of different liquids. Density is defined as mass/volume units $\ce$ 0.97, iodoethane 0.56, ethanol 1.07, cyclohexane 0.89, cyclohexanol 57.5, 1-propanol 1.945, ethylene glycol 16, glycerol 934.\). What are the Examples of Viscosity Answer: Some of the viscosity examples are: Viscosity shifts diversely under various temperature and weight conditions. The viscosity of a fluid is said to be low if it moves quickly. What makes them unique Why do they have properties that aren't easily replicated by other materials Let's start with a property that you are probably familiar with. ![]()
