1. Solids and Liquids
Chapter 14

2. Kinetic Molecular Theory
Solids-particles are highly ordered and packed closely together. They have slight vibrational movement. A solid maintains its shape regardless of the container.
Liquids-particles are more disordered and are spread further than in a solid. They more closely resemble solids than gases.

4. Phases Heat is added Heat is removed
Condensing-gas to liquid
Freezing-liquid to solid (0°C for water-freezing point)
Deposition-gas to solid (water vapor directly to ice)
Evaporation-liquid to gas (100°C for water-boiling point)
Melting-solid to liquid
Sublimation-solid to gas (dry ice directly to gas)

6. All phase changes are physical changes because a new substance is not created.

7. H bonding
H bonding-when H bonds with an electronegative element
Ex: H2S, HCl

9. Types of solids
Ionic-contains cations and anions, conduct electricity Ex: Salt (NaCl)
Molecular-contains covalent bonds (molecules) Ex: Sugar (C12H22O11)
Atomic-1 element covalently bonded to itself Ex: Diamond (Carbon)

13. Alloys
Alloy-a substance that contains a mixture of elements and has metallic properties.
Ex: sterling silver (93% silver, 7% copper)
steel (carbon and iron)
