• The properties of liquid can be understood by
• applying the kinetic-molecular theory
• considering the motion and arrangement of
  molecules
• the attractive forces between the molecules

Both liquids and gases are fluids takes the

Liquids have 1. Relatively high density 2.
Relative incompressibility 3. Ability to diffuse

Chapter 11.3 Solids

• Solids
• particles in relatively fixed positions
• more orderly arrangement, crystals

21
Crystalline solids - orderly, geometric
repeating pattern Amorphous solids - particles
are arranged randomly "supercooled liquids"
Crystalline solids have a definite melting point
amorphous solids do not.
