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 Definition: The form in which matter exists: solid, liquid, gas, or plasma Example: Ice = Solid Water = Liquid Helium = Gas Lightning = Plasma
5
Malleability Definition: The ability to be pounded into thin sheets Example: Aluminum can be pounded flat to make aluminum foil
6
Ductility Definition: The ability to be drawn into thin wires Example: Copper is used to make wires
7
Example: Sugar dissolves in coffee Kool Aid Solubility Definition: The ability for one substance to dissolve into another substance
8
Density 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 = 19.32 g/cm 3 (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
11
The Magic Triangle Answers are expressed in g/cm 3 or g/mL
