1. Physical Properties Liquids & Solids

2. Liquids vs. Solids LIQUIDS Stronger than in gases Y high N slower than in gases SOLIDS Very strong N high N extremely slow IMF Strength Fluid Density Compressible Diffusion

3. Liquid Properties  Surface Tension attractive force between particles in a liquid that minimizes surface area

4. Liquid Properties  Capillary Action attractive force between the surface of a liquid and the surface of a solid watermercury

5. Types of Solids  Crystals: shape reflects arrangement of the particles  Crystalline - repeating geometric pattern covalent network metallic ionic covalent molecular  Amorphous - no geometric pattern decreasing m.p.

6. Types of Solids Ionic (NaCl) Metallic

7. Types of Solids Covalent Molecular (H 2 O) Covalent Network (SiO 2 - quartz) Amorphous (SiO 2 - glass)

8. Allotropes  Two or more different molecular forms of the same element in the same physical state  Different properties due to different structure
