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

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 ___________________
