1. Chapter 4 Lesson 1 States of matter
How do you describe a solid?
How do you describe a liquid?
How do you describe a gas?

2. SOLID
GAS
LIQUID

3. SOLID GAS LIQUID Definite Shape Definite Volume Indefinite Shape
Indefinite Volume

4. Solid

5. Solid Particles are tightly packed Vibrate in place 2 types
Crystalline –regular, repeating patterns
Amorphous – irregular pattern

6. Solid

7. Liquid

8. Liquid Fluid – substance that flows Takes the shape of container
Particles are free to move

9. Liquid Surface Tension
Molecules attract one another and pull together into a ball

10. Liquid Viscosity High Viscosity = SLOW Low Viscosity = FAST
Liquids resistance to flowing
High Viscosity = SLOW
Low Viscosity = FAST

11. Gas

12. Gas Volume Pressure Temperature
-Gas volume is the same as the container
-Particles colliding
- Measure of average energy of motion
- Particles fill empty space
- Increase in particles means increase of collisions, which means increase in pressure.
- High temp. = fast particles
-Keep spreading until whole container is filled
Pressure = Force/Area
