1. Properties of Matter
This ppt goes along with properties of matter web-quest

2. Matter All matter has two types of properties: Physical properties
Chemical properties

3. Physical properties
A physical property is a characteristic of a substance that can be observed without changing the substance into another substance.
(You can see it without changing what you’re looking at into something else.)

4. Physical Properties - Examples
Examples of extensive physical properties include:
Volume
Mass
Weight
Size

5. Physical Properties - Examples
Examples of intensive physical properties include:
Density
Melting point
Boiling point

6. Physical Properties - Examples
Other physical properties include:
Color
Hardness
Odor
Taste
State of matter
Texture
Luster (shine)
Flexibility
Heat conductivity
Electrical conductivity
Solubility (ability to dissolve in water.)
Shape
Viscosity
Ductility
Malleability

7. Physical Properties
Thermal Conductivity: The rate at which a substance transfers heat.
State: The physical form in which a substance exists, such as a solid, liquid, gas, plasma.
Solubility: The ability to dissolve in another substance. Ex: Flavored drink dissolves in H2O.
Ductility: The ability of a substance to be pulled into a wire. Ex: Copper is often used to make wire because it is ductile.
Malleability: The ability of a substance to be rolled or pounded into thin sheets. Ex: Aluminum foil.
Density: The ration of the mass of a substance to the volume of the substance.

10. Density Highlight Density is the amount of matter in a given volume
What is mass? Mass is the amount of matter in an object.
What is volume? Is the amount of space available for that material.
SO, density is the amount of material that fits into a particular amount of space.

11. Density Continued Different materials have different densities.
EVERY bit of material/substance has a specific density that is the same no matter how much of it you have or from where you get the sample.

12. Sink or Float
Density determines whether a substance will sink or float.
More dense= will sink
Less dense= will float.

13. Chemical properties
A Chemical property is a characteristic of a substance that can only be observed by changing it into a different substance.

14. Chemical Properties
Describes matter based on its ability to change into new matter that has different properties.
Examples of Chemical Properties:
Flammability: The ability of a substance to burn.
Reactivity: The ability of two or more substances to combine and form one or more new substances.

15. Chemical properties - Examples
The ability to burn
Ability to tarnish
Ability to rust
Ability to decompose
Ability to react with other chemicals
Instability
Ability to do acid/base reactions

16. Examples 1.Flammability 2. Reactivity
3. Combustibility: The measure of how easily a substance will set on fire, through fire or combustion.

17. Chemical and physical properties – So what?
Titanium is very strong and doesn’t rust, so it is often used in jet engines.
Titanium is also non-allergenic. This, combined with the fact that it is rust proof makes it great for artificial joints as well as piercings.

18. Chemical and physical properties – So what?
Helium is almost completely nonreactive (inert).
It is lighter than air, so it’s great for floating balloons (or making funny voices.)
When electricity runs through helium, it glows a creamy pale peach color.

19. Chemical and physical properties – So what?
In 1943, all US pennies were made of zinc plated steel because copper was being used in the war. The pennies had to be coated with zinc because steel will rust, but zinc won’t.

20. Chemical and physical properties – So what?
Sulfur smells awful. Rotten eggs, onions, and garlic all have sulfur in them. Stink bombs use sulfur to create a bad smell.
Sulfur is also flammable, and it is one of the 3 main ingredients in gun powder.

21. Chemical and physical properties – So what?
Chromium is famous for its intense luster. Chrome plated tools, jewelry, silverware, or car parts are very popular.

22. Law of Conservation of Matter
Matter cannot be destroyed nor created
Originally called the Law of Conservation of Mass.
Antoine Laurent Lavoisier is given credit for this discovery.
Einstein stated that the Law of Conservation of Matter was the same as the Law of Conservation of energy. Energy is in matter and matter is energy. E=mc2…(energy x mass x speed of light squared).

23. Changes in Matter
All matter, regardless of state, undergoes physical and chemical changes.
Physical changes-will change the visible appearance without changing the composition of the matter.
Chemical changes-will change the composition of matter and will create a new substance. These changes are irreversible.

24. Changes in Matter Description Is it Physical? Is it Chemical?
Burning coal
Mixing salt & pepper
Dissolving sugar in tea
Melting an iron rod
A can rusting
Cooking scrambled eggs
Water freezing into ice cubes
Fireworks exploding
Sawing wood to make a cabinet
Bread baking
Digestion of Food
Getting a haircut
Lighting a candle
The evaporation of water off your skin
Tarnishing silver
Ice cube melting
Formation of acid rain
Crushing rocks
Blow drying your hair
