1. Properties of Matter
Section 3.1

2. What is Matter? Matter – anything that has mass and volume
Everything you can see and touch is made of matter
Only things that aren’t matter are forms of energy – light and sound.

3. Mass Mass – the amount of matter in a substance or object.
SI units – grams, kilograms

4. Mass vs. Weight
The more matter an object contains, the more it weighs.
Weight – a measure of the force of gravity pulling on an object.
A scale is used to measure the force pulling down
SI unit – Newton (N)
Example: 1kg weighs 9.8 N (2.2 lb)

5. Volume Volume – the amount of space matter takes up
Liquids measured in graduated cylinders.
Irregular shaped objects use water displacement.
Measured in liters, mL, m3, cm3

6. Displacement Method

8. Properties of Matter Physical Properties Examples
describe matter without changing its identity
Examples
color, shape, size, density, melting point, and boiling point

9. Physical Properties

10. Density
Density – physical property, represents how tightly packed particles of matter are.
D = Mass/Volume

11. Chemical Properties
describe how a material will react to form something new
Examples
flammable (can burn)
can corrode (metals combine with metals  dull, brittle
can sour
forms precipitate (solid forms from 2 liquids)
reacts with acid
effervesces (forms bubbles of gas, NOT BOILING)

12. Reactivity
Reactivity – the ability of matter to combine chemically with other substances.
Example – iron reacting with oxygen to produce rust.
