5. 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.

6. 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)
