1. The Physical Properties of Matter

2. What is a physical property of matter?
A property that can be observed or measured without changing the identity of that matter
Ex: Color, odor, shape, size, etc.

3. Thermal Conductivity
Definition:
The ability to transfer thermal energy (heat) to something else
Example:
Coffee in a special cup to prevent heat transfer to our hands

4. State The form in which matter exists: solid, liquid, gas. Definition:
Example:
Ice = Solid
Water = Liquid
Helium = Gas

5. The ability to be pounded into thin sheets
Malleability
Definition:
The ability to be pounded into thin sheets
Example:
Aluminum can be pounded flat to make aluminum foil

6. Ductility The ability to be drawn into thin wires
Definition:
The ability to be drawn into thin wires
Example:
Copper is used to make wires

7. Solubility
Definition:
The ability for one substance to dissolve into another substance
Example:
Alka-seltzer dissolves in water or sugar dissolves in coffee

8. Density Mass per unit volume
Definition:
Mass per unit volume
Example:
Lead is used for fishing weights because it is more dense than water

9. More information about density...
Density = The amount of matter in a given space or volume
Density = m Mass
v Volume

10. More information about density...
Most substances have a unique density:
Water = 1.00 g/mL
Gold = g/mL
(See page 13 in your book for a bigger list)
Density < 1 - The object will float in water
Density > 1 – The object will sink in water

Answers are expressed in g/cm3
or g/mL
