1.2 Investigating Matter Notes
There are 2 types of changes in matter:
Chemical Change
A chemical change is a _____________________ change in matter that occurs when _____________
combine to form ______________ substances.
We say a _____________________________ has been formed because the ___________________
are rearranged into different __________________________.
-
Both ______________________ and _________________________ properties are changed
-
Changes ___________________ be reversed
Clues that a chemical change might have occurred:
1
______________ change
2
______________ produced
3
_____________________________ energy given off
4
Changes are not easily _________________________
** Remember these are only clues that a Chemical Change may have occurred
Examples of chemical changes?
Physical Change
In a physical change, no ________________________________ are created. The ______________
do not rearrange.
Physical Changes involve changes in ____________________, ______________________, or
_____________.
-
No __________________ produced by the substance
-
Physical changes are generally _____________________________
Examples of Physical Changes include:
Properties of Matter
Properties, or more properly, _________________ of matter are characteristics of matter
that can be ________________ or ________________.
Characteristics that can be observed are called __________________ properties.
Characteristics that can be measured are called __________________ properties.
The set of properties that a particular substance has is unique. No other substance has that
same set of properties. Thus, unknown substances can be identified by the set of properties
they have.
Some properties include:
Qualitative
State
Colour
Malleability
Ductility
Crystal Structure
Magnetism
Quantitative
Solubility
Conductivity
Viscosity
Melting/Freezing Point
Boiling/Condensing Point

Matter = anything that has ________________ and ___________________
Kinetic Energy = ________________________________
KINETIC MOLECULAR THEORY
 Explains what happens to matter as the _____________________ of the particles
_________________ or ___________________
 _________________________________
Four main points to the KMT:
1
All matter is made up of very small _________________________
2
There is __________________ between the _______________________
3
The particles are constantly _______________________________
 Solids – particles are packed __________________ and ____________________
- hold a definite ______________________
 Liquids – particles can ______________________________ past each other
- can’t hold a ___________________________ so a liquid takes the shape of the
_______________________
 Gases – particles have large ____________________ between them
- particles are moving quickly in all _____________________ and spread out to fill the
container
