Topic: MATTER and Its PHASES
Essential Question: What is matter and how does MATTER change from one phase to the next?
QUESTIONS:What is matter?
How is weight different from mass?
What is volume? How is it similar or different from mass?
Identify the phases of matter. What do you do to change the phases of matter?
Describe Kinetic energy of particles in solid, liquid, gas and plasma?
Compare and contrast exothermic and endothermic reaction / Matter-It’s what the world’s made of. Ex. __desk______; ______water______; plants
Matter is anything that has ___Mass______and ___Volume______
Mass is the ____amount of matter______in an object
Units of mass: (triple beam balance is used to measure mass)
1.)mg – milligrams
2.)g-grams;
3.)kg- kilograms –SI unit (International System)
Weight – force exerted on an object due to ___gravity______
-Is equal __mass x acceleration__ due to gravity (9.8m/s2) on earth
Volume – is the ___space______the matter takes up
Units of volume: (graduated cylinder)
1.)L- liters SI unit
2.)mL – milliliters– liquid used a graduated cylinder; 1,000mL = 1L
3.)cm3 – cubic centimeters– solid (ruler method)
4.)gallons

4 Phases of Matter:
- SOLIDSSolids hold their own ___definite shape_____.
Have very ___little ENERGY_(Kinetic energy)______
Examples: __rock______; ____concrete__; ___cement__; ice_
- LIQUIDS Liquids take the ____shape/form of container_.
Have __Medium Energy____ levels
Examples: __water______; _soda______; __vinegar_; milk_
- GAS gases ____spread out____ to fill the entire space given
Have __high level______of energy
Examples: ___carbon dioxide___; ___oxygen____; __Nitrogen_gas (70%)____
- PLASMAare _____electrically______charged
Levels
_Lightning______is a plasma
Used in fluorescent __light_ ____bulbs______and ___neon______lights
Plasma is a lot ___like______gas______but the particles are electrically charged.
Phase in which matter is extremely high in energy, and
cannot be contained by ordinary matter, __very __
_____rare_on Earth.
ENERGY determines the State of Matter. (Copy the diagram- see the board)
ADDITION of ENERGY to MATTER:
When ENERGY is added, particles move _Faster______!
When energy is taken away, particles move ____Slower______!
a.)SOLID + Energy = ____LIQUID_____
Examples: _____ice to water______
b.)LIQUID + ENERGY = ____GAS______
Examples: ___water to water vapor (boiling)_____
c.)GAS + Energy = ___PLASMA______
Example: ___metals heated__
REMOVAL of ENERGY from MATTER:
a.)Plasma – Energy = ______GAS______
b.)Gas – Energy = ______LIQUID______
c.)Liquid – Energy = ______SOLID______
PHASE CHANGES of MATTER:
a.)__Freezing______phase change from liquid to solid
b.)__Melting______ phase change from solid to liquid
c.)__Condensation____change from gas to liquid
d.)___Vaporization______change from liquid to gas Ex. boiling
e.)__Evaporation_____ vaporization that takes place at
the surface of a liquid.
f.)___Sublimation______ change from the solid phase directly to the gas phase.
Ex. Solid Carbon dioxide (CO2) Dry ice sublimes
g.)Ionization – gas to plasma
h.)Recombination – plasma to gas
