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.

A brief tutorial which defines a dipole-dipole force, and explains how to identify which molecules exhibit dipole-dipole forces.

[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.

A tutorial on covalent bonds and intermolecular forces. A good summary weak forces, including Van der Waals forces and an excellent illustration showing the relative strengths of different forces and bonds.

[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...

Have you ever wondered why oil and water don't mix? Discover why some substances dissolve in water while others don't.

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

The temperature at which substances boil is determined by intermolecular attractions. Explore how these forces affect a substance's boiling point.

This article, published by Scientific American (June 19, 2000), explores how geckos hang on vertical surfaces. They don't use glue, or suction, or even nature's version of Velcro. Instead, they utilize intermolecular forces "to get a...

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.

Read about the many properties of liquids. Take an assessment when finished.

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

This PDF shows many examples of organic molecules and functional groups.

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

Create a molecular bond and observe energy over time.

This lesson focuses on chemical compounds including Ionic and Covalent Bonds, Valences, Lewis Structures, Binary Covalent Compounds, Radicals or Polyatomic Ions, and much more. It also includes a compound worksheet in which the students...
