Solids and Liquids
In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the...

Intermolecular Forces
In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces. He then explains how differences in these forces account for different properties in solid, liquids and gases. Some of these properties...
