Zihin haritası özeti: Solids I Crystalline-Amorphous

Solid Properties
- Energy & Order
  - Lowest energy state
  - Most ordered arrangement
- Physical Characteristics
  - Fixed shape & volume
  - Hard & incompressible
  - Vibrational motion only
- Thermal Behavior
  - Specific melting point
  - Volume expansion
Amorphous Solids
- Random particle stacking
  - No specific shape
  - No crystalline order
- Properties
  - Glass transition temp
  - Softening vs melting
  - No fixed melting point
- Examples
  - Plastics, butter, wax
  - Rubber, glass
Crystalline Solids
- Unit cell lattice
  - Geometric arrangement
  - Ordered particles
- Ionic Crystals
  - Opposite ion bonds
  - Example: NaCl
  - No electrical conduction
- Metallic Solids
  - Electron sea model
  - Mobile free electrons
  - Conducts heat & current
  - Examples: Fe, Au, alloys
- Covalent Crystals
  - Continuous bonding
  - Diamond & graphite
  - Quartz
- Molecular Solids
  - Weak intermolecular forces
  - Hydrogen bonds
  - London & dipole forces
  - Examples: H₂O, sugar, CO₂
Electrical Conductivity
- Metallic solids conduct
  - Iron, magnesium examples
- Ice doesn't conduct
  - Molecular solids weak
- Graphite vs diamond
  - Carbon form dependent
Classification System
- Two main categories
  - Crystalline ordered
  - Amorphous random
- Crystalline subdivisions
  - Ionic, metallic, covalent
  - Molecular type
Melting Point Distinction
- Crystalline specific
  - Ice: 0°C
- Amorphous range
  - Butter softens gradually
  - Not instant transition
