Viscosity increases with stronger intermolecular forces Step-by-step explanation: Viscosity is the resistance of a liquid to flow. Because they affect the surface properties of a liquid, soaps and detergents are called surface-active agents, or surfactants. There are strong and weak forces; the stronger the force… They effect the boiling point and freezing points. What intermolecular forces are present in #CH_3OH#? Intramolecular hydrogen bonding is partly responsible for the secondary, tertiary, and quaternary structures of proteins and nucleic acids, key molecules important to sustaining life. The following are two of the ways in which intermolecular forces affect the properties of a liquid: Melting and boiling point: Generally, compounds that undergo hydrogen bonding melt and boil at higher temperatures than compounds that experience dipole-dipole forces or London dispersion forces. -cP is a convenient, unit because the viscosity of water … Viscosity is defined to be a resistance to flow (like t maple syrup compared to water). Intermolecular Forces Viscosity • Resistance of a liquid to flow is called viscosity . Viscosity decreases rapidly with increasing temperatures because the kinetic energy of the molecules increases, and higher kinetic energy enables the molecules to overcome the attractive forces that prevent the liquid from flowing. Stronger IMFS would cause _____ viscosity. Intermolecular Forces. The stronger the intermolecular forces are, the tighter the molecules are held together and the higher the viscosity. 11.8 Network Covalent Solids —in some solids, covalent bonds extend throughout a crystal. The greater the inter-molecular forces the higher the boiling point and the higher the freezing point. Viscosity is also related to the strength of intermolecular forces. Forces Intermolecular Forces Affect Many Physical Properties The strength of the attractions between particles can greatly affect the properties of a substance or solution. Viscosity (η) is the resistance of a liquid to flow. Cohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface). Name some of the important molecules made possible by hydrogen bonding. Such solids, known as network covalent solids , generally are harder, have much higher melting points, and are less volatile than other molecular solids. How does viscosity depend on intermolecular forces? what other factors affect viscosity?-resistance of a liquid to flow-viscosity is measured in a unit called poise (P), defined as 1 g/cmS. FQ: How do intermolecular forces affect the properties of molecular compounds? How do intermolecular forces affect viscosity? The intermolecular forces between molecules in the liquid state vary depending upon their chemical identities and result in corresponding variations in various physical properties. Cohesion is the attraction in a molecule of liquid to each other due to intermolecular forces. A liquid can flow easily only if the molecules can move past each other with little resistance. The intermolecular forces in a liquid partially determine its viscosity, or resistance to flow. How would the strength of intermolecular forces affect viscosity? The stronger the intermolecular forces the higher the viscosity, molecules are closer together and get tangled up and become resistant to flow.
