3. Matter
Anything that has mass
and takes up space
Everything around us

4. States of Matter
Physical forms of matter, either solid, liquid or gas.
Also known as Phase Changes

5. States of Matter
Solids are a form of matter that have their own definite shape and volume
Liquids are a form of matter that have a definite volume but take the shape of the container
Gases have no definite shape or volume. They expand to fill their container.

6. States of Matter
Solids
Liquid
Gas

10. Physical Properties of Matter
TWO TYPES OF PHYSICAL PROPERTIES
Extensive properties:
Dependent on the amount of substance present
Mass

11. Physical Properties of Matter
Intensive properties
Independent of the amount of substance present

13. Chemical Properties of Matter
The ability or inability of a substance to combine with or change into one or more other substances.
Are not obvious unless the substance has changed composition

14. Chemical Properties of Matter
Examples of Chemical Properties
Flammability
Combustibility
Reactivity

15. Physical Changes of Matter
The ability of a substance to undergo changes that cause the appearance to be different without changing the composition of the substance.

16. Physical Changes of Matter
Examples of Physical Changes
Cut
Tear
Folded
Painted
Dissolve
Water Cycle
Mixture
Melt
Evaporate

17. Any change between solid, liquid and gas is ONLY PHYSICAL!!!!
Physical Changes of Matter
Most Physical Changes are REVERSIBLE
Any change between solid, liquid and gas is ONLY PHYSICAL!!!!

18. Physical Changes of Matter

19. Chemical Changes of Matter
A process that involves one or more substances changing into a new substances with different composition and different properties

20. Chemical Change of Matter
Examples of Chemical Changes
Gas Production
Color Change
Energy – Absorbed or Released
Not easily reversed
Odor Changes
Oxidized (Rusting)

21. Chemical Change of Matter
Chemical Changes are Chemical Reactions
Law of Conservation of Mass
States that mass is neither created nor destroyed during a chemical reaction
Mass reactants = Mass products
