Components of the mixture are not uniform or have localized regions with different properties. Ex. Pizza, blood, soil, etc.
H2O
Sample of Matter. with both definite and constant composition.
Changes of the State of Matter
<--- Freezing
Substance that cannot be broken down by chemical means. Ex. H, Fe, Cs, Fr, etc.
=
Condensation --->
<--- Ionization
Fusion --->
<---Sublimation
Example:
Magnesium 1. State: Solid 2. Symbol: Mg 3. Color: Silver 4. Element.
Chemical species formed when two or more atoms join together chemically. Ex. NaCL, H2O, etc
Deposition --->
Electricity
Components that make up the mixture are uniformly distributed throughout the mixture. Ex. Air, steel, suger water, rain water, etc.
H2 + O2
Deionization --->
+

Matter Properties and changes
Physical Change
A transformation in a physical property that retains the dentity of the substance.
Physical Properties: 1. Melting Point 2. Vapor Pressure 3. Color 4. State of Matter 5. Density- d= m/v 6. Molecular Mass 7. Electrical and Heat Conductivity 8. Solubility 9. Absorption into a surface 10. Hardness
Chemical Change
A transformation in which the original substance is converted to one or more new subtances.
Chemical Properties: 1. Reaction with acids 2. Reaction with bases (alkalis) 3. Reaction with oxygen 4. Reaction with... (a lot of more things) 5. Ability to act as axidizing agent 6. Ability to combust 7. Ability to act as a reducing agent 8. Reaction with another elements 9. Decomposition into smaller substances 10. Corrosive
Five States of Matter
Bose-Einstein Condensate
Characterized by: 1. Atoms cannot longer bounce around as individuals. 2. Atoms act in exactly the same way. 3. In 1924, Einstein and Bose, predicted a 5th state of matter which occurs at very low temperatures. 4. Discovered for the first time in 1995 by Wolfgang Ketterle
Plasma
Characterized by: 1. Result of rise in temperature of a gas. 2. Gas made up of particles carrying electric charge. ( ionization of gas at higher temperatures).
Gas
Characterized by: 1. No definite shape 2. Expand to occupy the entire available volume. 3. Molecules are all over (very separated).
Liquid
Characterized by: 1. They take the shape of the container which contains them. 2. Occupy a specific volume. 3. Molecules are separated.
Solid
Characterized by: 1. Structural rigidity. With a determined shape. 2. Resistance to changes of shape or volume and difficult to deform (in some cases). 3. They occupy a specific area or volume. 4. Molecules are compressed.
Biotic and Abiotic Factors
Abiotic Factors
Non-living physical and chemical factors which affect the ability of organisms to survive and reproduce.
Examples of Abiotic Factors 1. Virus 2. Crystals 3. Rocks 4. Volcano 5. Stars
Biotic Factors
All the living thing or their materials that directly or indirectly affect an organism in its environment.
Examples of Biotic Factors 1. Human 2. Mold 3. Oysters 4. Coral 5. Bacteria 6. Morning Glory
