Coming together, those two things put the European Central Bank in a real bind. Fight one fire and it could cause the other to flare. The ECB can keep raising interest rates to try to get inflation under control, but that risks fueling financial market tensions.

7.1: Surface Tension, Viscosity, and Capillary Action

WitrynaIntermolecular forces are attractive forces that hold neighboring molecules together. Intermolecular forces affect the physical properties of molecules. The strength of attractive intermolecular forces increases with an increase in melting point, boiling point, viscosity, solubility, and surface tension. WitrynaThe amount of energy needed to increase the surface of pentane is the smallest because pentane molecules interact by dispersion forces only. Therefore, the surface tension of pentane is the weakest. Table 1.

WitrynaSurface tension - resistance to distortion at the surface of the liquid from poking; The core principle is that the stronger the IMFs in the sample of molecules, the more strongly they interact, which means they stick together more. That leads to the following trends: Stronger IMF #-># Higher melting and boiling points (harder to melt and boil)

WitrynaSurface Tension Surface tension is the amount of energy required to stretch or increase the surface of a liquid. Molecules at the surface are less stable because they are only held together by molecules on one side. Surface tension results from the need to minimize the amount of surface to a liquid.
