How do imfs affect viscosity
WebMay 5, 2024 · How is viscosity of a liquid related to its structure? As Table 2 shows, the more structurally complex are the molecules in a liquid and the stronger the IMFs between them, the more difficult it is for them to move past each other and the greater is the viscosity of the liquid. How are viscosities of common substances related to cohesive forces? WebCHEM 162 (Barrows) Chapter 18 Notes Spring 2024 Page 9 of 34 Physical Consequences of Intermolecular Forces The strength of the forces between molecules of the same type dictates whether a particular compound is solid, liquid, or gas at room temperature, as well as how high or low its melting and boiling points are. Atoms that have stronger IMFs are …

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? WebIntroduction. The properties of liquids are intermediate between those of gases and solids, but are more similar to solids. In contrast to intramolecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, intermolecular forces hold molecules together in a liquid or solid.Intermolecular forces are generally much …
WebThe surface tension and viscosity values for diethyl ether, acetone, ethanol, and ethylene glycol are shown here. Explain their differences in viscosity in terms of the size and shape of their molecules and their IMFs. Explain their differences in surface tension in terms of the size and shape of their molecules and their IMFs. Answer a Answer b 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 • …
