Floating Squares  
Graphite (from a pencil lead) is applied to one side of an index card and a piece of the card is immersed in a beaker containing hexane and water (two layers). The graphite-coated side always faces the hexane layer. When the two liquids are carbon tetrachloride and water the graphite-coated side always faces the carbon tetrachloride.

Vapor Pressure of a Mixture: Raoult's Law  
The measurement of pressure exerted by a vapor is demonstrated using barometers. Vapor pressure varies with the strength of the intermolecular forces in the liquid. In this section we will look at vapor pressure of mixtures. We can calculate the vapor pressure of a mixture using Raoult's law.

Hardness of Solid Substances - Grinding  
A number of metals and nonmetals are ground with a mortar and pestle. The nonmetals shown here are all soft (due to weak intermolecular forces), but the metals vary in hardness.
