Imfs and surface tension
Did you know?
Witryna23 lut 2016 · Since hydrogen bonds are the strongest intermolecular force, the molecules of water are going to have higher surface tension than the molecules of the mineral oil. Mineral oil is non-polar, therefore the only interaction it can achieve would be a London Dispersion Force, resulting in super low surface tension. http://ch301.cm.utexas.edu/imfs/liquids/liquid-props-all.php

WitrynaFigure \(\PageIndex{3}\): Surface tension (right) prevents this insect, a “water strider,” from sinking into the water. The IMFs of attraction between two different molecules … WitrynaSurface Tension Surface tension is the amount of energy required to stretch or increase the surface of a liquid. Molecules at the surface are less stable because they are only held together by molecules on one side. Surface tension results from the need to minimize the amount of surface to a liquid. The stronger the IMFs, the higher …
WitrynaThis lab activity is meant to help students understand and better visualize IMFs, including London dispersion, hydrogen bonding, and dipole-dipole. I do this as an activity before I teach about surface tension and other properties of water. I am much less worried about students getting "the right an...
