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

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

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

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.

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)

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

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.

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
