Floating Squares   
(Movie/Animation, Audio/Visual (5))
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.
Magic Sand   
(Movie/Animation, Audio/Visual (5))
The grains of Magic Sand have been specially treated in a way that greatly reduces the attraction of water molecules to their surfaces.
Denaturing Proteins   
(Movie/Animation, Audio/Visual (3))
Egg white proteins are denatured by acid, lead solution, and heat.
Vapor Pressure of a Mixture: Raoult's Law   
(Movie/Animation, Audio/Visual (2))
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.
Vapor Pressure: Molecular Size   
(Movie/Animation, Audio/Visual (2))
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.
Hydrophobic Effect   
(Movie/Animation, Audio/Visual (2))
Hydrophobic Effect: Octanoic acid forms a monolayer on the surface of water under certain conditions.
Vapor Pressure: Molecular Size   
(Movie/Animation, Audio/Visual (2))
The vapor pressures of pentane, hexane, and heptane are compared. The vapor pressures of methanol and ethanol are compared. Molecular models of the compounds are shown.
Like Dissolves Like - Multimedia Experiments   
(Movie/Animation, Audio/Visual (18))
There are a total of six experiments you can view. You can view them in any order, as many times as you wish. Each experiment has three steps.
Electrostatics Attraction (GCMP)   
(Interactive Simulation, Software (1))
Electrostatics Attraction: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will correlate molecular polarity with the attraction of liquids to a charged rod. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
Intermolecular Forces (Netorials)   
(Instructional Material (1))
Intermolecular Forces: this is a resource in the collection "Netorials". In this resource there is a review of Lewis structures, molecular geometry, electronegativity, or molecular polarity. After that, you can learn about the forces of attraction that exist between molecules. This module explores London forces and dipole-dipole forces (including hydrogen bonds). The Netorials cover selected topics in first-year chemistry including: Chemical Reactions, Stoichiometry, Thermodynamics, Intermolecular Forces, Acids & Bases, Biomolecules, and Electrochemistry.
