How do imfs affect viscosity
WebWhat is viscosity and how do IMFs affect it? a measure of a fluids resistance to flow ( quick flow = low viscosity/ slow flow = high viscosity ) Stronger the IMF = greater viscosity … WebJan 24, 2024 · This means that larger molecules will feel more force, thus increasing the intermolecular forces. So if we have two molecules that are exactly the same, except that …

WebI can relate IMF to different physical properties of a substance Web-almost incompressible -assume the shape, not the volume of the container -molecules are held together more closely than gas molecules, but not so rigidly that the molecules can't slide past one another describe the structure and properties of a solid. -incompressible, definite shape and volume -molecules packed closely together
WebFeb 9, 2011 · Anemia can lead to decrease blood viscosity, which may lead to heart failure. Other factors influencing blood viscosity include temperature, where an increase in temperature results in a... WebNov 29, 2014 · The higher the vapor pressure will be if the IM forces are weak. higher the vapour pressure will be if the IM forces are weak. the vapour pressure is the pressure exerted by vapour molecules on a solid/liquid surface with which it is in a state of equilibrium, which means as long as there is an equilibrium, vapour molecules enter the …
WebDefinition: Intermolecular Forces Forces that explain why molecules stay near one another. IMFs control the physical state of a substance. The strength of an IMF affects the properties of the substance. Gases have weak IMFs, and solids have strong IMFs. Types of Phase Changes Fusion (melting): solid to liquid, energy absorbed WebIMFs are the various forces of attraction that may exist between the atoms and molecules of a substance due to electrostatic phenomena, as will be detailed in this module. These …
