2)Compare and contrast amorphous solids and crystalline solids?
3)What is the temperature at which a solid becomes a liquid and what is this process called?

4. Structure of a Solid
-Attractive forces tend to hold the particles of a solid in a relatively fixed positions, with only vibrational movement.
-Has a definite shape and volume
-Unlike liquids, solids have a much more ordered structure.

5. Solids Come in 2 Forms
Crystalline Solids- These solids consist of crystals or groups of crystals fused together, and are held together by their crystal structure. These particles are organized in a coordinate system called a lattice. b
Amorphous Solids- Solids that are not arranged into regular patterns. Formed in a way that prevents crystalline structures from taking shape. Examples of such solids include glasses and plastics.

6. Other Information -Solids have a definite melting point.
-Solids have various molecular structures, some of which form crystalline substances.
-If a solid lacks this rigid structure, but its still has other properties of a solid, it is considered an amorphous solid.
