1. Behavior of Matter
Chapter 2.1 & 2.2
Pages 44-55

2. Different States of Matter
What are defining characteristics of the 3 main states of matter?
Shape
Volume
Energy
Different States of Matter

3. Particles in a solid have energy – they are NOT motionless
The particles in a solid vibrate back and forth.
Energy in Solids

4. Liquid Particles Liquids or any matter that can flow is called a fluid
A fluid’s resistance to flowing is called Viscosity.
Liquid Particles

5. The viscosity of a lava flow determines the type of eruption
“Runny” lava is calmer eruption
High viscosity is typical of explosive eruption.

6. V, T… Volume is the amount of space that matter fills Temperature is…
mL or cm3
Temperature is…
a measure of heat or energy
Speedometer for particles.
V, T…

7. Pressure is the force of a gas pushing out over the area of its container
P = Force / Area
And P…

8. P = Force / Area Boyle’s Law When pressure increases, area… decreases
When pressure decreases, area
increases
Inversely Proportional
Boyle’s Law

9. Temperature & Pressure
How do particles behave when you add heat to a gas?
Particles have more energy and therefore move faster
How does this affect pressure?
As temperature increases, pressure increases – directly proportional
Why?
An increase in temperature = increase in energy = increase in force!
Temperature & Pressure

10. When adding heat to a gas, what happens to its area?
Charles’ Law states that when temperature increases, area increases
