Florida State University: Intermolecular Forces: Changes of State

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Johannes Diderik van der Waals won the Nobel Prize for physics in 1910. The video, part of the Socratica chemistry playlist, explains what the van der Waals forces are and how they interact based on type. It details dipole interactions...

The three states of matter are the focus of this chemistry video. Sal uses the example of a water molecule, and explains in great detail what forces are present to make that molecule change back and forth between a liquid, a solid, and a...

Article from Michael Blaber and Florida State University. Amorphous and crystalline solids are compared and contrasted. The unit cell arrangements and the packing of unit cells into crystalline solids is explained and colorfully...

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

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

Explore DNA in this tutorial. Learn about its structure, function, and why it is considered the universal code.

This tutorial reviews the principles of the cell theory. The cell theory states that all organisms are made of cells. These cells are the smallest and basic unit of life. And finally, cells can only come from other cells.

Explains what each of the four fundamental forces is and their interactions with the physical world. The four types are the strong force, the weak force, the electromagnetic force, and the gravitational force.

Explore the differences between chemical and physical changes, including some examples at the atomic level.
