1. I will identify the states of matter and describe their characteristics.

2. I will show what changes of states can occur.

Success Criteria

I can describe the states of matter and how they change.

Learning Target

States of Matter

1. All matter is made of small particles. (atoms, ions, molecules, etc.)

2. Those particles are in constant random motion. 

3. This motion causes the particles to collide with each other and the container that they are in.

Kinetic Molecular Theory

the measure of the average kinetic energy of particles in an object

• The higher the temperature, the higher the kinetic energy, the greater the motion of the particles

​

Temperature

Fixed volume and fixed shape

- Particles are held tightly together in a rigid structure

- Particles have low kinetic energy. Because of this, particle motion is limited to vibration

Solid

​​ ​ Fixed volume but shape changes based on container it is in

- Particles have more kinetic energy than solids

- Particles can flow or slide past each other

Liquid

No fixed volume or shape 

- If confined, gas particles will spread out to fill the container called diffusion

- Particles have high kinetic energy 

- Energy is high enough to overcome any forces that hold the particles together

- Particles can freely move

Gas

​Three States of Matter

Plasma

Matter composed of positively and negatively charged particles with extremely high kinetic energy

• Most common form of matter in the universe

• Makes up stars, neon lights, auroras

Condensation

​Changes in States of Matter
occurs when there is a change in thermal energy

Exothermic Process
(Releasing Heat; Getting Cold)
- Decomposition
- Condensation
- Freezing
Endothermic Process
(Absorbs Heat; Getting Hot)
- Sublimation
- Vaporization
- Melting
