WitrynaIntroduction. The properties of liquids are intermediate between those of gases and solids, but are more similar to solids. In contrast to intramolecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, intermolecular forces hold molecules together in a liquid or solid.Intermolecular forces are generally … Witryna1 mar 2024 · The quality responsible for oil being "slippery" is called lubricity and it is very different from viscosity- although many oils that have high lubricity are also more viscous than water.. In very general terms, lubricity has to do with the ability of the lubricant to withstand being subjected to extremely high pressures in the gaps … sometimes macbook wont turn on

Witryna21 sie 2024 · Viscosity is the resistance of liquids to flow. Viscosity increases with 1) stronger intermolecular forces and 2) decreasing temperature. Surface tension results … WitrynaThe 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 that do not flow freely, like those shown in Figure 7.1.1, have higher viscosities. We …

WitrynaViscosity is resistance to flow. For liquids, typically the larger the intermolecular forces (IMF) the higher the viscosity. The other factors that affect viscosity are temperature and the shape of the molecule. Higher temperatures will correspond to higher average kinetic energies and faster moving molecules. This will lead to a lower viscosity.
