[Free Registration/Login may be required to access all resource tools.] The following online tutorial describes how the electronegativity difference between two atoms in a covalent bond results in the formation of a nonpolar covalent,...

A presentation on intermolecular forces. Click the desired topic to view a PowerPoint slideshow.

This article from the Florida State Univeristy provides good information on the various intermolecular forces, including nice diagrams.

Learn that boiling point, solubility, and DNA are affect by intermolecular forces in this module. Module includes lessons with questions and animations to explain London dispersion and dipole-dipole attractions. To conclude the lessons,...

Students will study temperature changes caused by the evaporation of alkenes and alcohols and relate this data to the strength of intermolecular forces of attraction. They will also predict, and then measure, the temperature change for...

This lesson will define intramolecular forces and intermolecular forces and explain the difference between them. It is 1 of 2 in the series titled "Intermolecular and Intramolecular Forces."

This simple interactive tool lets students explore the forces of attraction between polar and non-polar molecules.

[Free Registration/Login Required] Explore intermolecular forces by seeing how many drops of a liquid a penny can hold.

Simulations that explore different attractive forces between polar and non polar molecules.

Discusses the changes of state that can occur for the three different types of matter (solids, liquids, and gases) and different types of heat energy that have been defined by scientists.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe a liquid according to the kinetic-molecular theory. They will also learn how a liquid exhibits surface...

Students discover intermolecular attractions between neighboring molecules. These intermolecular attractions, or IMA, affect the behavior of liquids, solids, and solutions.

A discussion of the variety of forces which hold molecules together. The relative strengths of these forces for the various states of matter is discussed. The effect of such forces on the boiling points and other phase change...

Adjust the peeling force in this simulation to see how the van der Waals bonds break while peeling a piece of duct tape off of a surface.

Adjust the strength of interatomic interactions in this virtual bullet experiment. Observe how the adjustments in strength affect the material in the experiment.

Particulate level simulations that show only solute particles are convenient, since they focus student attention on the molecules of most interest. However, such solute molecules move in a Brownian manner. This simulation helps students...

Concept animation compares molecular movement of solids, liquids, and gases.

Observe the intermolecular interactions of a hypothetical multi-gear nanoscale machine.

This lesson will explain how to identify molecules that exhibit hydrogen bonding. It is 1 of 2 in the series titled "Hydrogen Bonding Identification."

Observe how molecules can be sorted in a hypothetical nano conveyor-belt mechanism.

Create a molecular bond and observe energy over time.

Learners can use this web-based activity to study solutions, as far as the intermolecular attractive forces that allow or do not allow a solvent to dissolve in a solute. Also discussed includes the solubility rule "like dissolves like"...
