Physical and
Chemical
Properties
Matter
Matter is anything that takes up
space and has mass.
Matter can change in two ways
– physical or chemical.
Four States of Matter
 Solids
 Liquids
 Gases
 Plasmas
Matter
Matter can change from one state
to another by increasing or
decreasing temperature or
pressure.
Physical Change
1.
2.
3.
No new substance is created and the
original matter can be recovered.
A physical change does not change
what the matter is.
The substance may seem different,
but the way the atoms are linked up
are the same.
Physical Change
Physical changes include:
 Changing the shape or size
 Dissolving
 Changing from one state of
matter to another
By adding energy, the
state changes.

Examples of Physical
Change
 water
chopping wood
evaporating
 erosion
 clothes drying  rock breaking
in a dryer
 mixing Kool-Aid

Chemical Change
1.
2.
When a chemical change
takes place, a new substance
is made.
The matter can not be
changed back into its original
state.
Examples of Chemical
Changes
fruit rotting or
spoiling
 rust
 decay of plants

burning
 silver
tarnishing
 car burning gas
 baking bread
