WebIntermolecular forces (IMFs) are attractive interactions between molecules. They lead to differences and sometimes trends in various physical properties. Dispersion < Dipole-Dipole < Hydrogen-bonding < Ion-Dipole < Ion Pairing. Hydrogen- bonding (which is not bonding) is shown below in an example diagram for H2O and HF. 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. It's not actually floating, it's resting on top of the hydrogen bonds that exist between the water molecules …

A candle … WebMar 12, 2024 · 1 Answer Sorted by: 1 Capillary effects involve two things: the surface tension of the liquid itself ( gamma in your equation) and the contact angle of the liquid on a solid surface ( theta in your equation). High surface tension means the liquid is capable of clinging strongly to itself. chrome pc antigo

WebApr 23, 2024 · The effect of surface tension on capillary pressure is more complicated: on one hand, the capillary pressure is directly proportional to the surface tension. On the other hand, high surface tension liquids typically also have higher contact angles, which lower the capillary pressure. WebFeb 13, 2024 · Intermolecular forces determine bulk properties such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.
