States of Matter (Material World)

Why is glass sometimes called supercooled liquid? How does surface tension allow a water beetle to walk across the surface of a pond without sinking? How does an ice-skater's blade melt ice? In this book you will learn about the three main states of matter: solid, liquid, and gas. Discover how materials are used in these states and the stages a material goes through when a change in state occurs. Find out what a huge part the material world plays in your life! Each book in the 'Material World' series looks at a key area of materials science, covering subjects such as states of matter, material characteristics and behavior, the uses of different materials, and the technology used to make new materials or change existing ones for new purposes.
