Solids, Liquids and Gases Vibrating, Sliding, Zooming • All matter is made of tiny

Solids, Liquids and Gases Vibrating, Sliding, Zooming • All matter is made of tiny particles (atoms or molecules), which are in constant motion. • How tightly these particles are packed or bonded determines what state they take. © Kesler. Science. com

Solids, Liquids and Gases • Particles vibrate or move around more if the matter

Solids, Liquids and Gases • Particles vibrate or move around more if the matter is heated. • Particles vibrate or move around less if the matter is cooled. © Kesler. Science. com

Solids, Liquids and Gases Solids • Have a definite shape and a definite volume

Solids, Liquids and Gases Solids • Have a definite shape and a definite volume • Particles are tightly packed, vibrating about a fixed position. © Kesler. Science. com

Solids, Liquids and Gases Liquids • Have a definite volume, but no definite shape

Solids, Liquids and Gases Liquids • Have a definite volume, but no definite shape • They take the shape of their container. • Particles are tightly packed, but far enough apart to slide over one another. © Kesler. Science. com

Solids, Liquids and Gases • Have no definite volume and no definite shape •

Solids, Liquids and Gases • Have no definite volume and no definite shape • They take the shape of their container. • Particles are very far apart and move freely except when they collide. © Kesler. Science. com

Solids, Liquids and Gases Changes of State • Adding or removing thermal(heat) energy causes

Solids, Liquids and Gases Changes of State • Adding or removing thermal(heat) energy causes a change in state of matter. • States can change from one state to another. © Kesler. Science. com
