1. Properties of Matter
S8.C.1.1.2

2. Matter Anything that has mass and takes up space (volume)
State of Matter depends on how atoms are moving and interacting with each other
Solid
Liquid
Gas
Plasma -combination of gas atoms without electrons and free flowing electrons (ionized atoms)

3. States of Matter
Difference between particles in 3 states

4. Changing States of Matter (Phase Change)
Freezing pt = melting pt
Boiling pt = condensation pt
crystallization
Changing states by adding or removing heat
Evaporation
Add heat or remove heat for different substances
Condensation
Temperature converter

5. Solids Particles are tightly packed usually in a regular pattern
Particles vibrate, but cannot move past each other
Has a fixed shape
Has fixed volume
Not easily compressible (little space between particles)

6. Liquids Particles are close together with no regular arrangement
Particles can move slightly and slide past each other
Take the shape of its container
Has fixed Volume
Not easily compressible (little space between particles)
Jello?

7. Gas Particles are well separated with no regular arrangement
Particles move freely at high speeds
Take the shape of its container
Take the volume of its container
Compressible (lots of space between particles)

8. Physical Properties of Matter
Property that you can observe or measure without changing the composition (chemical makeup/ identity) of a substance
*Scientists can identify individual substances by their physical properties.

9. Physical Properties of Matter
Texture
Color (streak test)
Shape
Odor
Melting/Freezing pt
Boiling point
Magnetism
Mass
Weight
Solubility (ability to dissolve)
Volume
Density
Conductivity
Thermal expansion (Increase in volume when heated)
Thermal contraction (decrease in volume when cooled)
Video of expansion and contraction

10. Density Density= mass/volume Units for density= (g/cm3) or (g/ml)
How much “stuff” (mass) is in a certain amount of “space” (volume)
mass = gram (g)
volume = cubic cm (cm3) = milliliter (ml)
Density= mass/volume
Units for density= (g/cm3) or (g/ml)

11. Density All samples of the same substance have the same density
Song!
Rap!
All samples of the same substance have the same density
Water has a density of 1g/ml…no matter how much water you have
Objects with a density less than water will float in water
Objects with a density greater than water will sink
Water expands when frozen!
Because of its structure!

12. Finding Density
Density (g/ml)
0.5
0.8
0.75

13. Chemical Properties of Matter
Property that you can observe or measure only by changing the composition (chemical makeup or identity) of a substance
When chemical Reactions take place, the identity of the substance always changes
Examples :
Flammability
Ability to oxidize (rust) react with oxygen
Reactivity

14. Acids / Bases Litmus Paper An indicator for acid or base
Base will turn paper blue
Acid will turn paper red
