Some liquids, such as gasoline, ethanol, and water, flow very readily and hence have a low viscosity. Others, such as motor oil, molasses, and maple syrup, flow very slowly and have a high …
WebThe movement of fluid with high viscosity is sluggish or slow. The movement of fluid with low viscosity is quick. Viscosity is the relative property. If you consider air and water, water has a higher viscosity than air as the air feels … Web21 aug. 2024 · Viscosity increases with 1) stronger intermolecular forces and 2) decreasing temperature. Surface tension results from the net inward force experienced by the …
WebThe viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids … WebAs you go up the fractionating column, the hydrocarbons have: lower boiling points lower viscosity (they flow more easily) higher flammability (they ignite more easily) This means that in...

WebSurface tension is defined as the energy required to increase the surface area of a liquid or the force required to increase the length of a liquid surface by a given amount. This property results from the cohesive forces between molecules at the surface of a liquid, and it causes the surface of a liquid to behave like a stretched rubber ... financial hardships for college studentsWeb7 apr. 2024 · Both of them are dependent on molecular interactions. The viscosity of a fluid is a measure of how sticky the fluid is, on the other hand, Surface tension is the elastic property of a fluid which makes it acquire the least … financial hardship services australiaWebIt is not surprising that bulk viscosity is little known when the modern Handbook of Viscosity by C. Yaws [35] and the Handbook of Chemistry and Physics [7] do not mention it at all. Interestingly, it was noted by Stokes, and indeed known as the Stokes's hypothesis [ 22, 36 ], that there are a few compressible fluids, such as monatomic gases, where this … gsti back officeWeb19 aug. 2024 · The stronger the intermolecular forces, the more attracted the molecules in liquid are to each other and the harder it is to separate them to turn into gas (vapor). Therefore, for a liquid with strong intermolecular forces, not a lot of vapor will be formed and the vapor pressure will be low.
