1. How do you describe stuff And Identify it?
Properties of matter
How do you describe stuff
And
Identify it?

2. What is matter? Anything that has ____________
And occupies ________________
Which means has a ____________

3. Two kinds of properties
A Property is something we use to describe matter.
Non-characteristic properties
Gives lots of hints about an unknown piece of matter.
Characteristic properties
Identifies matter

4. Non-characteristic properties
A regular property or NON-characteristic property gives you hints about what a substance is.
If you have lots of them it can help you narrow down the choice but does not identify a substance.

5. Here are some examples Mass (measured in grams)
Volume (measured in mL)
State of matter (Is it a solid, a liquid or a gas?)
Temperature ( measured in 0C)
Acidity (is it acidic, basic or neutral)

6. Characteristic properties
Some properties are so special that they are only true for 1 substance.
We call these characteristic properties.
These properties are used to identify substances

7. Here are some examples Density Ratio of the mass to the volume D= M/V
(how much stuff is there in this space)
D= M/V
The temperature of a phase change
Boiling point
the temperature it is when it changes from a liquid to a gas.
Melting point
The temperature it is when it changes from a solid to a liquid.

8. To sum up Non characteristic Properties Characteristic Properties Mass
Volume
Temperature
Phase or state of matter
pH (acid, base ,or neutral)
Density (M/V)
Temperature of a phase change
