Unit 3: Intermolecular Forces and Properties
Topic 3.1 Intermolecular Attractive Forces
This link contains a guided inquiry approach, using questioning, to inventing dispersion forces, dipole-dipole forces and hydrogen bonding forces. This activity is for students, while the link below contains answers for the teacher.
This link contains a guided inquiry approach, using questioning, to inventing dispersion forces, dipole-dipole forces and hydrogen bonding forces. It also includes a movie depicting a model for London dispersion forces and some interactive simulations depicting particulate level models for the intermolecular attractive forces.
This link contains introductory leccture notes for intermolecular attractive forces.
A table of dipole moments and polarizabilty values for some simplee molecules.
Topic 3.2 Properties of Solids
Topic 3.3 Solids, Liquids and Gases
This link contains simulations by the Concord Consortium depicting a gas, a liquid and a solid.
Topic 3.4 Ideal Gas Law
This simulation is written in HTML5 by Pearson Publishing and should run on any platform.
How are the pressure and volume of a gas sample related? Answers
How are the pressure and temperature of a gas sample related? Answers
Topic 3.5 Kinetic Molecular Theory
This simulation is written in JAVA by Kirk Haines, John Gelder and Micheal Abraham and should run on PC (Help) or .jnlp file that will run on a Mac (Help). Anyone who is unsuccessful using the java version of the Gas Law program, or the .jnlp version can view movies of the java version using the links provided here: Pressure-Volume activity and Pressure-Temperature activity

How are the pressure and temperature of a gas sample related?
Topic 3.6 Deviations from the Ideal Gas Law
Topic 3.7 Solutions and Mixtures
This link contains introductory lecture notes for solutions. The notes contain movies of macroscopic examples of heterogeneous mixtures and homogeneous mixtures. There are also interactive simulations of heterogeneous mixtures and homogeneous mixtures, and a simulation showing an ionic compound dissolving in water. These notes also include a discussion of the solution process.
Topic 3.8 Representations of Solutions
Topic 3.10 Solubility
Topic 3.11 Spectroscopy and the Electromagnetic Spectrum
A tool, on the Academo website, to convert a wavelength in nm to an RGB, hexadecimal or HSL color. Academo is an online hub of interactive, educational demonstrations. It's free, open source, and available to all.
An interactive Web environment that allows building a molecule, generating an infrared spectrum and a Jmol molecule that displays modes of vibration and bending in the molecule. Very sophisticated. An article that describes the Web app (this article may not be accessible to everyone.)
