But, as readers of this insightful new book will learn, these things don't happen by accident. "States of Matter: Gases, Liquids, and Solids" deciphers the science behind these chemical states to present an engaging and eye-opening reference. This new title is enhanced by full-color photographs and illustrations, sidebars, a glossary, and a list of suggested Web sites and further reading.
