1. Chemical and Physical Properties

2. Matter All matter has 2 types of properties: Physical properties
Chemical properties

3. Physical properties
A physical property is a characteristic of a substance that can be observed without changing the substance into another substance.
(You can see it without changing what you’re looking at into something else.)

4. Physical Properties - Examples
Examples physical properties include:
Volume
Mass
Weight
Size
Density
Melting point
Boiling point
Density = mass per volume

5. Physical Properties - Examples
Other physical properties include:
Color
Hardness
Odor
Taste
State of matter
Texture
Luster (shine)
Flexibility – easy to bend
Heat conductivity – metals are good conductors
Electrical conductivity – metal are good conductors
Solubility – ability to dissolve a substance
Shape
Viscosity – thickness of a liquid
Ductility – ability to bend without breaking
Malleability – ability to fold into sheets
Luster = shine
Flexibility = ability to move
Solubility = ability to dissolve in water
Viscosity = liquid thickness
Ductility = ability to stretch into a wire
Malleability = ability to form a thin sheet by hammering or rolling

7. Chemical properties
A Chemical property is a characteristic of a substance that can only be observed by changing it into a different substance.

8. Chemical properties - Examples
Examples of chemical properties include:
The ability to burn -- flammability
Ability to tarnish – ability to corrode
Ability to rust
Ability to decompose
Ability to react with other chemicals
Instability – reactive in the air / water
Ability to do acid/base reactions
Tarnish = corrosion form over metal
Decompose = break apart chemically
Instability = the state of being likely to change
