Adhesive vs cohesive Cohesion refers to the forces of attraction within a substance. Another name for IMF Cohesive means things that are alike stick together. Adhesion refers to the forces of attraction between two different substances, usually a liquid and a solid. If adhesion is stronger than cohesion, then a liquid will spread out on a surface. If cohesion is stronger than adhesion, a liquid will bead up on a surface.

Intermolecular Station Lab Station 1 – Examine viscosity of liquids with hydrogen bonding. Swirling and shaking to compare flasks A and B. Identify substances. Station 2 – Compare states of substances with dispersion forces Identify substances C, D, and E. Station 3 – Compare surface tension of liquids Compare adhesion and cohesion of water and oil Station 4 – Compare evaporation rates of liquids Watching evaporation of single drops Identify substances F, G and H. Station 5 – Compare evaporation rates of liquids Comparing two kinds of wipes To create a “moist paper towel half”, dunk into beaker of water, then wring out as best you can Station 6 – Compare the solubility of polar and nonpolar substances in polar and nonpolar solvents 2 colored solids tested in 3 solvents (DEMO)
