1. The Physical Properties of Matter
Unit I – 1
Pages 44-47

2. What is Matter?
Matter is anything that has mass and occupies space

3. Properties
Characteristics or ways of describing things

4. Physical Property
Are usually those that we can observe with our senses
A substance's physical property allows us to identify the substance without causing a change in the composition of the substance.

5. Physical Property Some examples of physical properties are:
physical state (solid, liquid or gas at certain temperatures and pressures)
colour
odor
solubility in water (the ability of substance to dissolve in water)
density
melting point / boiling point
hardness
ductility
malleability
conductivity

6. Intensive or Extensive
A physical property can be intensive or extensive
Extensive property
depends on the amount of substance present
can not be used to id a substance
Eg. Mass and Volume

7. Intensive or Extensive
Intensive property
Depends on the nature of the substance not on the amount present
E.g. Boiling point/melting point/ density

9. Chemical Properties
Are those that relate to how the substance changes in composition
Or how it interacts with other substances.

10. Chemical Properties Some examples of chemical properties are:
paper burns
iron rusts
gold does not rust
wood rots
nitrogen does not burn
silver does not react with water
sodium reacts with water

12. Physical Properties
States of water

13. Three States of Matter
