Description

Why do atoms combine to form molecules? Why are substances solid, liquid, or gas? What happens when matter changes from one state to another? Professor Gerello flattens model atoms, making electron shell blueprints that show how electrons govern chemical change, and special effect photography illustrates molecular motion in solids, liquids, and gases. Also explains how adding or removing heat energy from matter increases or decreases molecular motion, resulting in a change in state.
