Particle Theory of Matter(See handout for a
complete list)

• Space The spaces between the particles are very
  large compared to the sizes of the particles
  themselves.
• Speed The particles in matter are in constant
  motion.
• Stickiness The particles in matter attract one
  another.

2
States of Matter

• Physical state is based on
• The nature of the bonds between the particles
  (potential energy, stickiness)
• The motion of the particles (kinetic energy,
  speed)

3
Solids

• Rigid
• Definite shape
• Definite volume

4
Solids

• Stickiness of bonds limits particle motion
• Particles vibrate in relatively fixed positions
  (low speed)

5
Solid State 4 particles
6
Solid State Multiple Particles
7
Liquids

• Definite volume
• Takes shape of container

8
Liquids

• Stickiness of the bonds is lower than in solids
• Particles have more speed than in solid state

9
Liquid 4 particles
10
Liquid Multiple Particles
11
Gases

• No definite shape
• No definite volume
• Takes shape of container

12
Gases

• Stickiness between particles is zero
• Greater speed than in solid and liquid states

Gas 4 particles
