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? _______
13
