PROPERTIES OF MATTER
1. A Substance may be identified by certain Qualities, or Traits. A QUALITY OR TRAIT THAT IDENTIFIES A SUBSTANCE IS CALLED A PROPERTY.
2. The property of a substance stays the SAME even if the Volume changes.
3. COLOR, MASS, SMALL, DENSITY, AND COMPOSITION ARE ALL EXAMPLES OF PROPERTIES THAT CAN HELP SCIENTIST IDENTIFY SUBSTANCES.
4. A PROPERTY THAT ALWAYS STAYS THE SAME IS CALLED A CHARACTERISTIC PROPERTY BECAUSE IT IS A CHARACTERISTIC OF A PARTICULAR KIND OF MATTER.
5. EVERY SUBSTANCE HAS TWO KINDS OF PROPERTIES - PHYSICAL PROPERTIES AND CHEMICAL PROPERTIES.
6. A PHSICAL PROPERTY is a property of matter that can be OBSERVED or MEASURED WITHOUT CHANGING the composition of the substance.
7. Physical properties are often used to identify substances.
8. SOME PHYSICAL PROPERTIES OF MATTER:
A. BIOLING POINT - The temperature at which a substance changes from a liquid to a gas.
B. CONDENSATION POINT - The temperature at which a substance changes from a gas to liquid; same temperature as boiling point.
C. DENSITY - The mass of a specific volume of substance.
D. FREEZING POINT - The temperature at which a substance changes from a liquid to a solid; same temperature as melting point.
E. MELTING POINT - The temperature at which a substance changes from a solid to a liquid.
F. RESISTANCE - The opposition of a substance has to the flow of electric current.
G. SOLUBILITY - The degree to which a substance will dissolve in a given amount of another substance, such as water.
