The stronger the intermolecular forces in a liquid, the higher the surface tension. e.g. The stronger the intermolecular forces in a liquid, the higher the viscosity. A liquid can flow easily only if the molecules can move past each other with little resistance. Q: What is the concentration of a weak acid if its K a =3.7 x 10^ -7 and its pH = 3.38 ? OTHER SETS BY THIS CREATOR. Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. Stronger intermolecular forces higher viscosity Image: CC BY 14.3 Properties of Water Electron dot formula for H 2 O: H 2 O has a bent molecular geometry with bond angle of < 109.5 honey flows slowly high viscosity; gasoline flows rapidly low viscosity. Viscosity increases with stronger intermolecular forces Step-by-step explanation: Viscosity is the resistance of a liquid to flow. The intermolecular forces between molecules in the liquid state vary depending upon their chemical identities and result in corresponding variations in various physical properties. phillipjcox PLUS. This is a small amount of gas that is found above all liquids. Stronger intermolecular forces → higher viscosity. Surface tension is a measure of the toughness of the surface of a liquid; Stronger intermolecular forces → higher surface tension. o Viscosity: the resistance of a liquid to flow. AP Chemistry: Intermolecular Forces, Liquids, and Solids Lecture Outline 11.1 A Molecular Comparison of Liquids and Solids Physical properties of liquids and solids are due to intermolecular forces. Capillary action is the net result of two opposing sets of forces: cohesive forces, which are the intermolecular forces that hold a liquid together, and adhesive forces, which are the attractive forces between a liquid and the substance that composes the capillary. Higher the intermolecular forces between the liquid particles, harder it is for it to escape into the vapor phase, ie., you need more energy to convert it from liquid to the vapor phase, in other words, higher its boiling point. Median response time is 34 minutes and may be longer for new subjects. Intermolecular Forces and the Viscosity: Intermolecular forces are the attraction forces between molecules of a compound. Physical properties of substances are understood in terms of kinetic-molecular theory. *Response times vary by subject and question complexity. ... How are viscosity and intermolecular forces related (at a given temperature)? Surface Tension. Refer to our lesson about vapour pressure to learn about it. • Intermolecular forces • Properties liquids • Crystal structure • X-ray diffraction • Types of crystals • Phase changes • Phase diagrams ... the viscosity, the fluid flows more slowly Intermolecular interactions are stronger in a fluid with bigger viscosity than in a fluid with smaller viscosity • Viscosity ( the resistance of a liquid to flow) increases. These are forces between molecules. 4 terms. The higher the intermolecular forces the higher the boiling point is. Cohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface). They might be strong in some compounds (like hydrogen bonding forces… Chapter 36 Relativity. Viscosity: resistance to flow. Vapour Pressure.
