Properties of Matter
*
Matter might be__________________________, rough or smooth, round
or square, hot or cold.

*
It may fit inside a ___________or be as big as the entire
_______________!
*
Matter may be any color of the rainbow, or no color at all.
__________________________________________________temperature,
flammability, size, and color are all examples of properties of
matter.
Can matter change properties?
Physical Properties
*
Physical properties of matter ______________________
*
For example: size, amount, ___________________________________
Chemical Properties
*
Chemical properties hold true for a particular kind of substance
no matter what the sample –
________________________________________
*
For example: boiling point, melting point,
______________________________________________
*
Because they never change, chemical properties can be used to
identify unknown matter
Matter Classifications
*
Matter can be classified into two general categories:
______________ and ____________________________
Mixtures
*
Mixtures consist of ______________________________that are mixed
together but __________ chemically combined.
*
In a mixture the individual substances ___________their
separate properties.
*
A __________________ is the “best-mixed” mixture of all
possible mixtures; it appears to be a single substance
*
Examples of mixtures: _________________________________
Pure Substances
*
Pure Substances are made of
_________________________________and have
________________properties.
*
_________________________ – a substance that cannot be broken
down into other substances by chemical or physical means
*
Examples: Hydrogen, Nitrogen, Aluminum, _________________
*
____________________ – a substance formed from chemical
combinations of two or more different elements
*
The properties of compounds are always __________________from
the properties of the elements that formed them
*
The element carbon typically exists as a
powdery________________; the element hydrogen and oxygen exist
as _______________________. These elements combine to form
compounds like sugar which is a
__________________________________________.

Examples: Water, __________________, and ___________________
