Matter&
Properties of Matter
Matteranything that has mass and takes-up space
the quantity of matter present
mixtures and substances
of the same kind
of different kinds
MatterMatter-
Mass-
All matter can be divided into two categories:
Homogeneous-
Heterogeneous-
Mixtures definitions
• CAN be separated by physical means(heating, cooling, sorting, filtering)
• Homogeneous & Heterogeneous
Mixtures
Mixture-
2 categories of mixtures:
More on MixturesHomogeneous: Example:
Heterogeneous:
Examples:
Mixtures definitions• is visibly the same throughout
Ex. salt water, Kool-Aid, milk
• is visibly different throughout; different samples may not be exactly alike
• ex. Salad dressing, chicken noodle soup
Pure Substance-
Two Categories: Element:
Example: Compound:
Examples:
CAN NOT be separated by physical means, ex: heating, cooling, sorting, filtering
Elements & Compounds contains one kind of matter Ex:hydrogen, oxygen, copper a substance made of two or more
elements that cannot be separated by physical means.
Ex: water, carbon dioxide, salt, and sugar
Organize the Hierarchy of Matter
Substance
Element: contains one kind of matterExample: hydrogen, oxygen, copper
Compound: a substance made of two or more elements that cannot be separated by physical means.
Examples: water, carbon dioxide, salt, and sugar
QuestionsAnswer A = True and B = False
1. Matter is anything that has mass and takes up space
2. Mass is the quantity of matter present
3. A mixture cannot be broken down by physical means
4. A substance cannot be broken down by physical means

States of MatterWhat determines the state of the
matter?Depends on the amount of energy of
the particles
Kinetic energy (Ek): energy of motion
How fast are the particles moving?Depends on temperature
Four States of Matter
Solid
Liquid
Gas
Plasma
States of Matter
Solid:Ek?molecular behavior?
Liquid:Ek ?molecules can slip out of their fixed position
States of Matter• definite volume, definite shape
LOW Ek
molecules vibrate in positiondefinite volume, NO definite shape (can change shape easily)Moderate amount of Ek
molecules can slip out of their fixed position
States of MatterGas: NO definite volume, NO
definite shapeHIGH Ek
molecules can move freely
Plasma: Most common state of matter in the universe, it is rarely found on Earth VERY HIGH Ek
