- Extensive Properties: property which depends on the amount of a substance present.
- Examples: mass, volume, length
- Intensive Properties: property which does not depend on the amount of a substance present.
- Examples: color, smell, hardness, density, physical state, boiling point, melting point, freezing point.
- Chemical Properties: properties which are measured or observable by changing the chemical composition or identity of a substance. Changes in color, generation of heat, precipitate formation, and gas generation are chemical changes which in turn change chemical properties.
- Examples: flammability, combustibility, corrosivity, oxidation.
- Chemical Changes “buzzwords”: burning, reacting, rusting, oxidizing.
- Physical Properties: properties that are measured or observable by not changing the chemical composition or identity of a substance.
- Example: color, mass, volume, density, hardness, physical state, temperature (melting point, boiling point, freezing point).
- Physical Changes “buzzwords”: tearing, pouring, boiling, freezing, melting, measuring
