WebApr 2, 2024 · 10.7: Viscosity. Because its molecules can slide around each other, a liquid has the ability to flow. The resistance to such flow is called the viscosity. Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength ... WebJan 30, 2024 · As temperature increases, the average speed of molecules in a liquid also increases and as a result, they spend less time with their "neighbors." Therefore, as temperature increases, the average intermolecular forces decrease and the molecules are able to interact without being "weighed down" by one another.

WebBlood pressure and components of blood viscosity were measured in 49 normal subjects and in 49 untreated patients with essential hypertension.
