states of matter - three primary states of matter: solid, liquid, and gas Solids - "Solids have a fixed volume and shape. The molecules that make up the solid have the shortest distance to travel until they collide with one another. This motion has been referred to as a "jiggle." Solids have a high degree of internal order; their atoms or molecules are limited to back-and-forth motion about a central position, as if held together by springs (see Figure 6-1, A). Solids maintain their shap...
