Study Notes
Intensive Properties
- Depend on the type of matter, not the amount present in a sample.
- Useful for identifying unknown substances.
- Examples include density, melting point, color, boiling point, ductility, malleability, odor, and solubility.
Extensive Properties
- Depend on the quantity of matter in a sample.
- Cannot be used for substance identification.
- Key examples include mass, volume, length, temperature, moles, energy, and width.
Key Definitions
- Mass: Quantity of matter in an object; extensive property.
- Volume: Space occupied by an object; extensive property.
- Length: Measurement of distance; extensive property.
- Density: Mass per unit volume; calculated by dividing mass by volume; intensive property.
- Melting Point: Temperature at which a solid turns into a liquid; intensive property.
- Color: Visual description of an object; intensive property.
- Boiling Point of Water: Transition temperature from liquid to gas; intensive property.
- Temperature: Average kinetic energy of particles in matter; extensive property.
- Ductility: Ability to be drawn into wires; intensive property.
- Malleability: Ability to be shaped into thin sheets; intensive property.
- Odor: Chemical property activating the sense of smell; intensive property.
- Width: Measurement of an object's width; extensive property.
- Circumference of a Soccer Ball: Example of an extensive property.
- Gold Density: 19 g/cm³, an example of an intensive property.
