States of Matter [PDF ebook] 

Many people are familiar with the states of matter called solid, liquid, and gas, but they may not have heard of the other two states, plasmas and Bose-Einstein condensates. In this notable book, readers will learn what all these states are as well as what happens to matter to trigger a change from one form to another. The comprehensible text is supported by helpful images, diagrams, and fact boxes as well as vocabulary that serves to highlight key science terms.
