How do imfs affect viscosity
WebProperties of Liquids: Viscosity • Viscosity is a liquid’s resistance to flow • Larger intermolecular attractions = higher viscosity • Stronger IMFs = higher viscosity • more spherical the molecular shape = lower viscosity (bc molecules roll more easily and Less surface-to-surface contact lowers attractions) WebFor example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires only about 17 kilojoules. However, to break the covalent bonds between the hydrogen and chlorine atoms in one mole of HCl requires about 25 times more energy—430 kilojoules.

WebStronger the IMF = greater viscosity (molecules held together so with strong IMF so don't want to break apart) How does temperature affect viscosity? Viscosity decreases as temperature increases Viscosity increases as temperature decreases When energy is added molecules more likely to move What is capillary action? WebProperties of Liquids Viscosity: liquid’s resistance to flow o Stronger IMFs = higher viscosity o more spherical the molecular shape = lower viscosity o higher temp = lower viscosity Cohesive forces: IMFs between identical molecules Surface tension: The energy required to increase the surface area of a liquid o Water has a high surface tension Capillary action: …
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 WebWhat affects viscosity? The IMF, higher the IMFs are the higher the viscosity is, size and shape of molecule, higher structural complexity of the molecule the higher the viscosity, temperature, higher temp= more KE= lower viscosity Surface tension Energy required to increase the surface area of a liquid What causes surface tension?
