1. Solid ___________________ Shape ___________________ Volume
Particles are ________________ in position (They vibrate)
___________________________ (Slowest moving particles)
Particles are closest together

2. Liquid _________________ Shape (Takes shape of container)
_________________ Volume
Particles are close together but have enough energy to slide past each other
________________________(Particles move faster than in a solid)

3. Gas ___________________ Shape (Takes shape of container)
___________________ Volume (Particles fill the entire container)
Particles are _________________________
Lots of energy (Particles move faster than those in liquids)

4. Plasma Super hot and gas-like
Can ________________________(made of negatively and positively charged particles)
Most common state in ________________________ (stars contain lots of plasma)
________________________(fastest moving particles)
Found in Lightning, Fire, Auroras, Gas Lights

5. THINK!!
What are the 4 different states of matter and how do they differ with respect to shape and volume??

6. Terms to Know Endothermic Exothermic
Process that ___________________________________________ from the surroundings
Feels __________________
Exothermic
Process that ___________________________________________ to the surroundings

7. Changes in States Gases and Liquids Liquids and Solids
_________________________ = liquid to gas = endothermic
_________________________ = gas to liquid = exothermic
Liquids and Solids
_________________________ = solid to liquid = endothermic
_________________________ = liquid to solid = exothermic
Gases and Solids
_________________________ = solid to gas = endothermic
_________________________ = gas to solid = exothermic
Plasma and Gases
_________________________ = gas to plasma = endothermic
_________________________ = plasma to gas = exothermic

8. THINK!!
What is the difference between an endothermic process and an exothermic process?

9. Phase Change Graph
Used to show ________________________________________________________________________ to change the phase of a specific substance
____________________________________ go with a single phase
Solid, liquid, or gas
____________________________________ go with a phase change (two phases are present at the same time like having a glass of ice water)
Freezing, melting, etc.
________________________________________________________________________ during a phase change.

10. Phase Change Graphs and Energy Changes
--Slanted lines indicate a ________ in temperature, therefore ________ Energy (Ek) is _________ (increasing or decreasing). --Horizontal lines indicate __________ in temperature, so Ekremains _______. However, energy is still being added or removed from the system. Therefore, __________ Energy (Ep) must be _________ (decreasing if a cooling graph where heat is removed, increasing if a heating graph where heat is added).

12. Why doesn’t the temperature change during that time?
THINK!!
How many states of matter are present for a horizontal line on a phase change graph? ______
Why doesn’t the temperature change during that time?
How many states of matter are present for a slanted line on a phase change graph? _______
