1. Characteristic Properties of Matter

2. How Are You Identified? Eye Color Hair Color* Skin Color Fingerprints
DNA
These are all characteristics you have that will stay with you for life and can be used to identify you.
*may change due to age or vanity

3. Matter is stuff First, A Quick Review
Matter is anything that has mass and takes up space.
Matter is the “stuff” (atoms and molecules) that makes up the universe
Matter is stuff

4. Examples of Stuff (aka matter)
Plants, animals, rocks, water, soda, air, oxygen are all examples of matter
Matter can be living or non living
Matter can be solid, liquid or gas
They are all made of atoms and molecules
They all have mass and take up space
They are all “stuff”. Yet all of the examples of stuff listed above are different
They all have different characteristics or properties that can be used to identify them
Characteristics of matter can be either physical properties or chemical properties

5. Characteristic Properties of Matter
Characteristic properties help scientists identify a particular substance
Characteristic properties are always the same for each kind of matter
Characteristic properties do not change even though the shape or amount of matter may change
Characteristic properties are like the eye color, hair color, skin color, fingerprints and DNA of matter

6. property= an attribute, quality, or characteristic of something.
physical property=A quality of a substance that can be observed or measured.
chemical property= A quality of a substance that has to do with the way it reacts with other substances

7. What Are Some Physical Characteristic Properties?
Physical properties can be
seen or measured without changing the identity of the substance
identified or described with your senses
Melting point, boiling point, freezing point
State of matter at room temperature (solid, liquid or gas)
Density
Magnetic properties
Solubility (will it dissolve in another substance?)
Conductivity (will it conduct heat, electricity)
Ductility, malleability (can it be drawn into a wire or pounded into a thin sheet)

8. What Are Some Physical Characteristic Properties?

9. What Are Some Chemical Characteristic Properties?
Chemical properties
may not be observed with your senses.
determines how a substance interacts with another substance.
determine if the substance can change into a new substance with different properties.
Flammability
Reactivity (how it behaves in the presence of another substance)
Oxidation (another word for rust and tarnish)

10. What Are Some Chemical Characteristic Properties?

11. Can You Identify? Physical Properties: Liquid at room temperature
Boiling point is 100 0C
Colorless
Density is 1 g/cm3
That was easy!

12. Let’s Try Another! Physical Properties Density is 8.96 g/cm3
Insoluble in H2O
Ductile, malleable
Chemical Properties
Oxidizes
Reacts with acids
Hint?
What do you think the flame is made of?
Does gold (Au) oxidize? How do you know?

13. Now You’re On Your Own
