7
Kinetic Theory

• All matter is composed of tiny particles
• Atoms
• Molecules
• Ions

8
Kinetic Theory

• These tiny particles are in constant motion.

9
Kinetic Theory

• Collisions between moving particles are perfectly
  elastic.
• In an elastic collision there is no net change in
  kinetic energy.

10
Pressure

• Pressure depends on two factors
• Force
• Area
• Pressure

Force Area
11
Examples of Pressure
12
Gas Pressure
13
Temperature

• How hot or cold
• Average kinetic energy

14
Absolute Zero

• K C 273

15
How do we lower temperature?

• We slow down the particles.

16
Kinetic Energy

• KE ½ mv2
• When considering kinetic energy we must consider
  two factors.
• Mass
• Velocity
