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

WebApr 23, 2015 · Stronger intermolecular forces will produce greater surface tension . The intermolecular forces present in a sample of water are hydrogen bonds . The high surface tension of water allows a paper clip to "float" on the surface of the water. 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 …

WebAs the temperature increases, the molecules move more rapidly and their kinetic energies are better able to overcome the forces that hold them together; thus, the viscosity of the liquid decreases. The various IMFs between identical molecules of a substance are examples of 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 …

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.
