Theory- Kinetic Particle Theory 8/2/13

Kinetic Particle Theory

Explained by:

• diffusion
• inter conversion of states
• Brownian Motion

Represented through:

• kinetic particles model

          -> explains particles' motion and arrangement in 3 states of matter

Example of particle motion

Physical Properties!! ( things that CAN be measure )

1. Volume
2. Mass
3. Density
4. Conductivity

x SHAPE    

x SIZE 

Mini Quizzz:

Use KPT to explain what happens to the particles

1. When an ice cubes melts
2. When water boils

When heat is supplied, water molecules gain energy and vibrate faster about their fixed position

When solid water molecules gain sufficient energy to overcome the hydrogen bonding that hed them in fixed positions,

the water molecules will move slightly apart and now roll and glide over each other (LIQUID)

Water  molecules gain energy, they move faster and further apart

When water molecules gain sufficient energy to completely overcome the hydrogen bonding between the molecules,

the water molecules move far apart and away from each other . (GAS)

melting point/ boiling point --> shows that heat is about to break up the bonding

* bond between water molecules = hydrogen bond 

Condensation

• loses heat to the surrounding

  - forms bonds

* think about freezing , condensation and sublimation

3 states of matter at different temperatures:
