2. SOLIDLIQUIDGAS Keeps it shape, particles arranged in pattern (rigid) Takes the shape of what you put it in, particles are close together but not arranged (less rigid) Overfills and moves out of container, particles not arranged (loose) Hard to change shape (will not compress, little space between particles) Not easy to compress (little space between particles) Can compress (lots of space between particles) Does not flow (particles do not slide past each other) Flows easy (particles slide past each other) Particles vibrate and move at high speeds

3.  Ice (H 2 O)  Has a regular shape  Hard to compress  Does not flow  Keeps shape if maintained below freezing temperature

4.  Water (H 2 O)  Takes shape of what it is poured into  Hard to compress  Flows easily  Keeps shape in container

5.  Water Vapor (H 2 O)  Does not take a definite shape  Can be compressed  Flows easily  Moves out or escapes container
